pequeno projeto foi criado depois que o autor teve alguns prejuízos com um cano
de água quebrado, que lhe custou o piso de madeira e alguns eletrônicos,
danificados pela água. Então para prevenir ele criou um sensor que detecta a

trabalham com componentes eletrônicos tem diversos modelos de caixas fica a sua
disposição escolher uma que melhor se adapte ao projeto, no caso deste foi
usada uma caixa de um carregador de bateria de celular Motorola, que ficou
muito bom, com espaço suficiente para os leds e para o buzzer na frente.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white; background-position: initial initial; background-repeat: initial initial; font-family: Arial, Helvetica, sans-serif;&quot;&gt;As ponteiras
podem ser feitas de qualquer material condutor, neste projeto preferi não usar
cobre, pois o mesmo se deteriora com o tempo, um bom material para usar é aço
inoxidável ou alumínio. No entanto as ponteiras devem manutenção periódica, verificando
as ponteiras e testando com água.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;background-color: white; line-height: 115%;&quot;&gt;&lt;/span&gt;&lt;br /&gt;&lt;/span&gt;

ponteiras usadas foram de alumínio, as ponteiras devem ser colocadas bem
próximas uma da outra, mas sem encostar, quanto mais próximas, mais sensível
será à água.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Temos aqui um circuito muito interessante que monitora a
bateria do carro indicando se está acabando. Funciona direto no sistema do
carro, usando 12 volts. Ele funciona como um voltímetro de escala expandida, indicando
pequenos espaços da tensão dentro de um intervalo, de 10 a 16 volts no caso, para
baterias de 12 volts.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
O coração desse circuito é o CI LM3914 N (CI1), que é um
indicador de tensão, ele faz a medição do sinal de entrada, mostrando então
sinal alto nas saídas de 1 a
10 de acordo com a tensão aplicada. O CI emite uma tensão estável de saída no
pino 7 de acordo com a referência interna, e este é alimentado por intermédio
do divisor de tensão VR2 e R2 para a referencia interna nos pinos de entrada 4
e 8, para ajustar o intervalo de sensibilidade em que o medidor opera. A
voltagem medida é alimentada no pino 5 através do divisor de tensão VR1 e R1.
Este divisor escala a voltagem para baixo, para um intervalo útil ao CI.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;

&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
É possível ajustar o medidor para ler os mesmos passos em escalas
de tensões superiores e inferiores. Podem ser usadas diferentes cores de LEDs
para representar os diferentes leveis de tensões. Será necessário uma fonte de
tensão ajustável e um voltímetro de boa qualidade para proceder com a calibração.
Conecte o voltímetro nos pinos 6 e 4 do CI, ajuste então VR2 até obter a
leitura de 1.2 volts. Agora concentre os ajustes em VR1 e VR3, se o intervalo
entre os terminais de VR1 é de 4.5 volts, então o circuito está pronto para
usar como monitor de tensão de baterias de 10.5 até 15 volts.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Conecte a fonte para proceder com os testes, ajuste ela de 9
até 15 volts e veja como o circuito se comporta, se não acender nada ajuste a
fonte em 12 volts e calibre o VR3 até que todos os leds verdes acendam, agora
ajuste a fonte até que apenas o primeiro led acenda, anote esta tensão, agora
ajuste a fonte até que o último led acenda, agora anote esta tensão e subtraia
da primeira, este é o alcance. Agora calibre VR1 e repita o ajuste anterior até
que a tensão de alcance seja de 4.5 volts. Depois deixe a fonte em 10.5 e
ajuste VR3 até que apenas o led mais baixo (D1) acenda.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Depois da confecção e calibração está pronto para o uso,
fica a critério de sua criatividade implementar uma caixa para ele ou ajustá-lo
no painel, apenas tenha cuidado para ligar as polaridades corretamente.&lt;/div&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Este circuito é um multímetro digital microcontrolado usando
um PIC 16F676, que vai ler o sinal analógico e mostrar o valor em 3 dígitos com
3 displays de 7 segmentos. Podendo ser usado também para medir a corrente DC
com um resistor de shunt em paralelo, não descrito aqui.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;
Como sabemos, a maioria dos microcontroladores PIC tem 8bit/10bit
no módulo conversor analógico-digital. Neste circuito teremos o PIC 16F676, que
possui ADC 10 bits e 8 canais, mas só usaremos 1 aqui, para medir. Os outros
pinos serão definidos como entradas e saídas digitais (digital I/O).&lt;/div&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
No esquemático, a tensão de entrada passa pelo divisor de
tensão ( R1 e R2), VR1 em paralelo com R2 é usado para ajustar a escala máxima
de tensão do display. A tensão depois do divisor irá se conectar ao AN3(RA4),
que está como entrada analógica.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
RA0, RA1 e RA2 estão como saídas digitais, para ligar e
desligar os dígitos na rotina de escaneamento do display. RA3 não foi usado, RC0
até RC5 e RA5 foram usados para controlar os displays de 7 segmentos.&lt;/div&gt;

rotina principal continua lendo a tensão de entrada no RA3 e converte para o código
de 7 segmentos , enquanto o TIMER 1 ajusta o timer para interromper a cada 5 ms
para escanear todos os dígitos em uma freqüência de 66Hz. Ao converter o valor
digital para a rotina devemos dimensionar o valor com a escala máxima mostrada
neste projeto que é de 30v, então a tensão de entrada será dimensionada em 30v.&amp;nbsp;&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
Circuito com 24 canais para acionar 24 leds, usa um
microcontrolador ATTYNI2313 (Atmel), e alguns componentes adicionais. O
principio fundamental é a indicação dinâmica, que é usualmente indicado para
controle de indicadores digitais de 7 segmentos. Aqui é o mesmo, mas ao invés
de indicadores de 7 segmentos usamos leds de 5 mm tradicionais.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
E para controlar tudo, o não muito caro ATTYNI2313, que pode
controlar o led diretamente (Até 20mA em cada pino ). Como você pode ver no
esquemático, os 24 leds estão reunidos em 4 grupos, e cada grupo com 6 leds. Os
leds do grupo 1 indicam o conteúdo do registrador R0 do microcontrolador, leds
no grupo 2 indicam o conteúdo do registrador R1, leds do grupo 3 indicam o
conteúdo do registrador R2 e os leds do grupo 4 indicam o conteúdo dos
registradores R3. Indicação dinâmica faz isso, como em cada momento do tempo
indica conteúdo de um registrador e escaneia o consecutivo. Por exemplo, quando
o conteúdo de R1 é carregado na port de saída (port b), o transistor Q2 entra
em condução, e o led do grupo 2 indica os bits em R1.&lt;/div&gt;

Foram usadas também 3 microchaves &amp;nbsp;“F”, “+” e “-“. O “F” é para mudar o efeito e
os de “+” e “-“ são para aumentar ou diminuir a velocidade do efeito. O
circuito pode ser alimentado com qualquer fonte DC de 8 a 15V por 100mA, pois usa um
regulador de tensão 7805, não é necessário usar dissipador de calor no
regulador.&lt;/div&gt;

O software foi escrito em assembler para IDE AVRStudio 4. O
código fonte se encontra abaixo. Com simples mudanças qualquer um pode
implementar uma série de efeitos, adicionando mais leds podem inclusive montar
uma iluminação para arvore de natal, ou iluminação para um letreiro de loja.&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 12pt;&quot;&gt;Este é um circuito PWM para controlar a ventoinha
(fan, cooler) de PCs, podendo assim eliminar sons desagradáveis, o circuito se
mostra muito simples que até uma criança poderia montá-lo.&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&lt;/span&gt;O circuito é composto de seis componentes: dois resistores,
dois capacitores, um potenciômetro e um transistor. O potenciômetro é ligado
como um divisor de tensão, os dois resistores irão definir o maior e o menor
valor para o divisor de tensão. A saída é conduzida diretamente para a base do
transistor de potência.&lt;br /&gt;
&lt;br /&gt;
Os capacitores serão usados como filtros, para suavizar
a tensão, pois foram detectadas algumas ondas nos testes. O C1 não é necessário,
foi posto apenas para evitar ruídos na base do transistor.&lt;br /&gt;

&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 12pt;&quot;&gt;Viu como é simples? Pode até ser montado em
placas de PCB pré-furadas, só tomando o cuidado de deixar o potenciômetro na
borda da placa, o circuito pode inclusive ser ligado em umas das saídas 12V da
fonte do computador.&lt;/span&gt; &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
A tensão de saída varia de 5V a 12V. No caso da sua
ventoinha não funcionar com uma tensão tão baixa, basta aumentar um pouco R3.&lt;/div&gt;

Há uma grande desvantagem embora, o circuito gera muito
calor no transistor, portanto é recomendável utilizar um dissipador de calor, o
único problema com isso é que o circuito não terá uma boa eficiência, mas
funcionará sem mais problemas. O transistor irá esquentar mais quando a
ventoinha estiver com uma rotação menor pois o transistor terá que dissipar
mais força, portanto o circuito é mais eficiente com uma rotação maior.&lt;/div&gt;

Um amplificador de áudio estéreo, construído com dois 7905,
que são reguladores de tensão negativos e outros componentes comuns, o circuito
poderá funcionar também com outros reguladores 79XX, se uma alimentação
apropriada for usada. O regulador de tensão 7905 funciona também como um
amplificador para as tensões aplicadas no pino 2 (GND). A queda de tensão
mínima padrão sobre o 7905 é de 2V, mas isso depende da corrente de saída.&lt;br /&gt;
&lt;br /&gt;
Os
resistores de realimentação definem o ganho do canal internamente. O
amplificador é um amplificador de áudio classe A. O valor mínimo aplicável ao
R3 para o 7905 é de 8,5 a
10 ohms por 5 W.&lt;/div&gt;

Se a corrente de saída exigida pelo LS1 for abaixo de 100 mA,
o valor de R3 pode ser de 33 a
51 ohms por watt. O circuito funciona com qualquer resistência de carga ( R3 em
paralelo com LS1 como carga)&amp;nbsp; sob a
condição que o regulador não esteja sobrecarregado com a dissipação de corrente
e potência. Contudo é preferível utilizar um auto-falante com uma resistência
alta ( 8 ohms, 16 ohms ou mais ). O amplificador funciona bem com fones com a
impedância baixa, com resistência de 24 a 32 ohms. A diferença de tensão entre o
pino GND do 7905 e o pino de saída é fixada internamente.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
S2 é chave de liga/desliga, S1 é o seletor entre mono e
estéreo, quando a chave S1 está fechada o amplificador trabalha como mono
bidirecional. Se S1 está aberta o amplificador trabalha como estéreo. Se nenhum
sinal é aplicado, a tensão de saída do regulador 7905 é por volta de -5V, que
depende do valor de VR1. Acorrente máxima de saída do 7905 é de 1A e a
dissipação de potência máxima é de&amp;nbsp; 15W,
é recomendável que utilize um dissipador de calor. &lt;/div&gt;

e durante a E3, o foco da Nintendo foi inteiro direcionado para o novo console
o “Wii-U”, nenhuma informação sobre um novo 3DS foi confirmada ou negada
durante o evento e pelas declarações de Shigeru Miyamoto não deveríamos esperar
esse Nintendo 3DS com novo hardware.&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 12pt;&quot;&gt;Mas para nossa surpresa a Nintendo acaba de
anunciar o novo hardware para o 3DS, sendo que o mesmo será uma cópia exata de
hardware diferenciando apenas o tamanho das telas que serão 90% maiores que o
DS atual, batizado de 3DS XL ( No Japão LL), estarão a venda nos EUA em 19 de
agosto, Japão e Europa um pouco mais cedo, 28 de julho. O 3DS XL contará com um
aumento na bateria também subindo para 6,5 horas a autonomia de jogo que antes
era de 5 horas, o 3DS XL ganha também um upgrade na capacidade de
armazenamento, que agora acompanha um cartão SD de 4 Gb, que antes era de 2Gb.
No Japão não acompanhará o carregador de bateria que é compatível com o 3DS
convencional, mas poderá ser adquirido separadamente, porém acompanhará o kit
vendido no EUA e na Europa.&amp;nbsp; &lt;/span&gt;&lt;/div&gt;

de $199,00 dólares, um acréscimo bem pequeno em relação ao atual que custa $170,00.
O lançamento do 3DS XL, coincide com o lançamento do jogo “New Super Mário
Bros. 2”. E
por enquanto sem previsões de lançamento aqui no Brasil.&lt;/span&gt;&lt;/div&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 12pt;&quot;&gt;O coração desse circuito detector de metais é o
CI &lt;a href=&quot;http://www.datasheetcatalog.org/datasheet/CherrySemiconductor/mXutsur.pdf&quot; target=&quot;_blank&quot;&gt;CS209A&lt;/a&gt;, que é um CI especial para a função de detecção a proximidade de
metal.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 12pt;&quot;&gt;&amp;nbsp;Teremos um indutor de 100uH, o &lt;a href=&quot;http://www.datasheetcatalog.org/datasheet/CherrySemiconductor/mXutsur.pdf&quot; target=&quot;_blank&quot;&gt;CS209A&lt;/a&gt; tem um oscilador que forma um
circuito LC, a indutância no indutor mudará quando ele for aproximado de objetos
de metal.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
O led vai então acender e o buzzer vai soar quando o indutor
mudar a indutância. Circuito de fácil montagem e regulagem.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
VR1 deverá ser
ajustado com uma certa distância de algum objeto de metal, até que o led acenda
e o buzzer soe, então ponha ele na distância desejada e vá mudado o VR1 até que
ele desligue o buzzer e o led, aquele ponto então será o ponto onde ele irá
indicar a distância máxima para soar, mais longe que essa distância ele não irá
detectar.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;

Você acha que a sua TV é grande? Acho que você não viu nada
ainda.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
A nossa forma de ver TV no futuro não irá mudar tanto, mas a
maneira como ela será disposta fará toda a diferença. Ela irá envolver todo o
ambiente dando ao espectador uma experiência de imersão total, podendo
inclusive visualizar em partes diferentes da sua tela programas de TV, filmes,
páginas da web, twitter e etc...&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;Mas como organizar toda essa TV gigante e com toda essa experiência
de imersão?&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Esse tipo de pergunta que empresas americanas de
Pay-per-view vêm fazendo, eles dizem que as emissoras já deveriam estar pensando,
pois na próxima década essa tecnologia estará a disposição do público, ainda
frisando o quanto a ficção acertou em prever em diversos filmes a tecnologia
que viria a ter a nossa televisão moderna.&lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
E toda essa previsão sobre a proximidade dessa tecnologia
estar sendo usada no quotidiano dos lares se deve ao fato do avanço na tecnologia
das telas de “organic light emitting diode” (OLED), analistas prevêem que essas
telas estarão a um preço acessível a maioria da população &amp;nbsp;de 5
 a 10 anos. As telas OLED têm uma grande vantagem sobre
as de LCD, elas não precisam de luzes laterais, então a área de exibição da
imagem pode ir até a borda da tela, podendo assim ser colocadas uma ao lado da
outra para criar um único painel continuo.&lt;/div&gt;
&lt;br /&gt;

As primeiras TVs OLED de 1.4 metro, estarão
chegando ao mercado no final do ano a 8000 dólares, mas a previsão é que sofram
uma rápida deflação e em menos de 2 anos esteja custando 3000 dólares. Modelos
custando 1000 dólares ou menos devem estar disponíveis de 5 a 10 anos.&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Veja bem que ao lado do conector USB da placa temos 3 pinos,
nestes pinos devem ser encaixado o jumper para o modo de alimentação, via USB (
quando está conectado no computador) ou da fonte externa que que vem inclusa
com o arduino. Para o procedimento seguinte usaremos a conexão USB então
encaixe o jumper como na imagem abaixo.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;

Procure por &lt;b&gt;Ports (COM &amp;amp; LPT), &lt;/b&gt;&lt;b&gt;&lt;span style=&quot;font-weight: normal;&quot;&gt;em seguida por &lt;/span&gt;USB
Serial Port (COM), &lt;/b&gt;&lt;b&gt;&lt;span style=&quot;font-weight: normal;&quot;&gt;o número do “COM” pode variar, mas sempre será algo como COM3 ou COM4.O
COM é para comunicação, e cada uma é um número único, neste caso o “COM port
number” é o COM3. Se você não encontra o Número da port COM, verifique se o Arduino está conectado.&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;

O que é o arduíno? Para quem não o conhece, simplificando,
ele nada mais é do que uma placa de desenvolvimento utilizando um
microcontrolador Atmel, possuindo inúmeras entradas e saídas para conexão com
sensores, leds, motores e etc... Enfim, uma gama de dispositivos e componentes
cuja sua imaginação é limite da criatividade para o que você pode fazer com ele.&lt;/div&gt;

&amp;nbsp;A
placa arduíno se assemelha muito a uma placa de desenvolvimento já mostrada
aqui no blog, na qual era utilizado um microcontrolador PIC, você pode &lt;a href=&quot;http://eletronica-indice.blogspot.com.br/2012/06/placa-de-teste-para-pic.html&quot; target=&quot;_blank&quot;&gt;conferir aqui&lt;/a&gt;. Você pode comprar um arduíno com a placa já pronta ou pode construir de forma
caseira a sua placa, temos um tutorial explicando como construir você mesmo uma
placa, &lt;a href=&quot;http://eletronica-indice.blogspot.com.br/2012/05/tutorial-de-como-fazer-uma-placa-de.html&quot; target=&quot;_blank&quot;&gt;confira&lt;/a&gt;. O projeto de hardware do arduíno está a disposição para &lt;a href=&quot;http://arduino.cc/en/Main/Hardware&quot; target=&quot;_blank&quot;&gt;download no site&lt;/a&gt;
deles podendo inclusive ser alterado, pois está sob licença open-source, o arduíno
pode ser conectado diretamente no seu computador via USB, o software pode ser
baixado também no &lt;a href=&quot;http://arduino.cc/en/Main/Software&quot; target=&quot;_blank&quot;&gt;site deles&lt;/a&gt; gratuitamente. Em breve estarei postando alguns
projetos utilizando o arduíno.&lt;/div&gt;

Nesse artigo tentaremos então dar algumas dicas para o
sucesso na montagem desse projeto. O projeto é baseado em uma das habilidades
do microcontrolador PIC16F628 em produzir pulsos PWM. Variando a largura de
pulso podemos produzir milhões de cores apenas combinando as três cores básicas.
Para isso usaremos um led RGB (red-green-blue), que é capaz de produzir todas
essas diferentes cores.&lt;/div&gt;

Com a ajuda de quatro chaves podemos alternar as diferentes
funções da luminária. Podemos definir se queremos troca lenta entre as cores ou
um salto brusco, temos também o modo de troca consecutiva entre as cores ou troca
aleatória, também pode definir se as trocas serão mais lentas ou mais rápidas e
podemos também pausar em alguma cor especifica.&lt;/div&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;

&lt;b&gt;A luminária&lt;/b&gt;&lt;/div&gt;

Como invólucro para receber as cores você deve escolher o
que achar melhor, no projeto original o autor usou um de 45 cm obtendo um resultado fantástico,
mas também podemos usar outros menores, isso fica a seu critério.&lt;/div&gt;

Na montagem uma boa maneira de fixar a placa na luminária é
usando uma pistola de cola quente, o calor da cola quente não é suficiente para
danificar os componentes do circuito.&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
O circuito repelente de cães e gatos que estou deixando a
seguir, se trata de um transmissor ultra-sônico de saída de alta freqüência cuja
intenção é atuar como repelente de cães e gatos, mas pode ser usado para
repelir outros animais. Não é aconselhável a ser usado como defesa contra cães
agressivos, mas pode ajudar a distraí-los ou encoraja-los a ir embora.&lt;br /&gt;
&lt;br /&gt;
Este repelente ultra-sônico usa o CI1, que é um CI 555
padrão, para gerar uma onda quadrada de 40KHz através de um circuito RC. Esta freqüência
é inaudível para seres humanos, mas é reconhecida por ser uma freqüência muito
irritante para cães e gatos. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
Uma vez que a corrente máxima que um temporizador 555 pode
fornecer é de 200mA, então um estágio amplificador foi necessário, uma
ponte H foi incrementada, formada por 4 transistores TR1 ao TR4. Um segundo
timer 555 o CI2, forma um amplificador de buffer que alimenta uma das entradas
da ponte H com uma forma de onda invertida a que o CI1 alimenta a entrada
oposta da ponte H.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span class=&quot;hps&quot;&gt;&lt;span lang=&quot;PT&quot;&gt;Isto
significa&lt;/span&gt;&lt;/span&gt;&lt;span lang=&quot;PT&quot;&gt; &lt;span class=&quot;hps&quot;&gt;que a condução&lt;/span&gt; &lt;span class=&quot;hps&quot;&gt;ocorre através dos&lt;/span&gt; &lt;span class=&quot;hps&quot;&gt;pares&lt;/span&gt; &lt;span class=&quot;hps&quot;&gt;complementares de&lt;/span&gt; &lt;span class=&quot;hps&quot;&gt;TR1/TR4&lt;/span&gt; &lt;span class=&quot;hps&quot;&gt;e&lt;/span&gt; &lt;span class=&quot;hps&quot;&gt;TR2/TR3&lt;/span&gt;
em marcas e espaços alternados, efetivamente dobrando a tensão através do transdutor
ultra-sônico LS1. Isto é otimizado para gerar uma saída alta, em frequencias
ultra-sônicas.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span class=&quot;hps&quot;&gt;&lt;span lang=&quot;PT&quot;&gt;&amp;nbsp;O
repelente é ativado usando um botão comum (switch S1), para controlar o consumo
de corrente, mas outras formas de ativação podem ser usadas usando para
automatizar o acionamento. Este circuito pode ser usado por exemplo, para
impedir que cães ou gatos destruam seus jardins ou canteiros de flores, ou que
entrem dentro de casa.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

time ganhou um premio em dinheiro de 200.000 baht (1baht = 0.031671 dólares), e
irão representar a Tailândia no “World Robocup Soccer Humanoid League”, a copa

Mais um projetinho simples de ser executado mas com uma idéia bem interessante. Se trata de um levitador magnético, ele é composto por um eletro-ímã que mantém objetos suspensos a uma distância préviamente ajustada. A física por trás desse projeto é simples o eletro-imã produz uma força de atração sobre o objeto igual e oposta a força da gravidade atuando sobre ele, portanto se anulam, como consequência disso o objeto fica suspenso no ar, flutuando.&lt;br /&gt;
&amp;nbsp;O circuito regula a distâcia do objeto ao ímã atravéz dos sensores, diminuindo ou aumentando a força que o ímã faz, de acordo com a proximidade do objeto.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
O circuito funciona comparando o sinal vindo dos sensores com o primeiro amplificador operacional e mandando uma voltagem proporcional a diferença, ou erro. O sinal de erro é enviado através de uma rede de compensação que funciona como filtro de passa-alta. Permitindo que as rápidas mudanças de erro passem mais facilmente do que as lentas. Isto é necessário para estabilizar o controle de loop. Sem ele os objetos flutuariam apenas perto do eletro-imã, o que faria o sistema ficar instável. O sinal é então amplificado para a sua amplitude original, desde que a rede de compensação o tenha atenuado, o que faz com que o transistor TIL 122 controle a corrente do eletr-imã. Os diodos perto do transistor são para prevenir danos no mesmo. O diodo na base é para impedir a polarização revesa, enquanto os outros 1N4001 são para impedir a corrente reversa que flui quando o eletro-imã é desligado. Os ^ngulos de detecção e emissão não são tão estreitos, os Led emissores de infra são TIL 38 que tem 940nm de pico e 15 graus de propagação, 35mW e 100mA. Os detectores são PT204-6B que são foto-transistores receptores de infra.&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
O detector de cima é a referencia e o de baixo detecta quando o objeto está na posição de levitação. o Led emissor então tem que estar na mesma direção do receptor de baixo. O eletro-imã deve ter no máximo 15 ohms de resistência, mais que isso não vai ser capaz de levantar nada. Muito menos resistência e o transistor vai ter dificuldade para regular o ímã e vai gerar muito calor. Quando estiver montando o ímã deve se lembrar de duas coisas. A força magnética é proporcional ao número de espiras e a corrente. Então quando você estiver usando fio de cobre, a força magnética será proporcional ao quadrado da força dissipada nele para todo uso prático. Nesta bobina foi usado 70m de fio de 0.45mm. E pode ser enrrolado em qualquer haste de metal ferroso se não estiver muito preocupado com a eficiência.&lt;/div&gt;

Temos aqui um circuito detector de vazamento de gás, ele detecta o vazamento e alerta o ususário com indicações audio-visuais.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
O circuito opera com uma bateria de 9v. Um diodo zener ZD1 é usado para converter 9v em 5v para alimentar o módulo sensor de gás.&lt;/div&gt;
&lt;/div&gt;
&lt;br /&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;
O circuito detector de vazamento usa um módulo sensor de gás SEN-1327 da empresa RhydoLABZ. Ele sinaliza quando a concentração de gás excede um certo limite. Um preset no módulo é usado para acertar o limite. A interface com o módulo é feita através de 4 pinos utilizando padrão SIP.&lt;/div&gt;

Os detalhes dos pinos estão mostrados na figura a seguir. No módulo sensor de gás é usado um MQ-6, que é o sensor de gás. Ele pode ser usado para detectar gases combustíveis, principalmente metano.&lt;/div&gt;

Quando a concentração de gás em uma área chega a 1000ppm (partes por milhão), o pino OUT do módulo indica sinal alto, esse sinal é lançado em um CI 555, que está em uma formação de multivibrador astável, que vai basicamente funcionar como um gerador de tons. O pino de saída 3 do CI 555 está ligado ao Led 1 e ao transistor SL100, que é o controlador do auto-falante, através dos resistores R4 e R5, que funcionam como limitadores de corrente. O led então pisca enquanto soa o alarme, para avisar do vazamento de gás. O ton do alarme pode ser mudado variando VR1. Recomenda-se usar um dissipador no SL100.&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://eletronica-indice.blogspot.com/feeds/6316533648242638165/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://eletronica-indice.blogspot.com/2012/06/circuito-detector-de-vazamento-de-gas.html#comment-form' title='2 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/3170100248610955706/posts/default/6316533648242638165'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/3170100248610955706/posts/default/6316533648242638165'/><link rel='alternate' type='text/html' href='http://eletronica-indice.blogspot.com/2012/06/circuito-detector-de-vazamento-de-gas.html' title='Circuito Detector de Vazamento de Gás'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiweQ2FeQ9k7wiXz0uCm8Hu5Denl7y5aUGWIjNbK6yWopTYFTnNt0lwOF6iaJrkWov1qZXF4BdLXPsd1pqCC_5CImn6QBqooxMU0WeRdT8DUWPTlGQ97yXagNz8woM_uviwYC8rmdqeKZ4/s72-c/gas-leak-detector-schematic.jpg" height="72" width="72"/><thr:total>2</thr:total></entry><entry><id>tag:blogger.com,1999:blog-3170100248610955706.post-3305779526839661854</id><published>2012-06-11T01:24:00.000-03:00</published><updated>2012-07-06T23:11:46.726-03:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="Eletrônica"/><category scheme="http://www.blogger.com/atom/ns#" term="Microcontrolador"/><category scheme="http://www.blogger.com/atom/ns#" term="Programação"/><category scheme="http://www.blogger.com/atom/ns#" term="tutorial"/><title type='text'>Tutorial Atmel</title><content type='html'>&lt;div style=&quot;text-align: justify;&quot;&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
Esta é uma placa de teste 2 em 1, pois pode tanto gravar quanto para experimentar microcontroladores PIC de 40 pinos. Muito fácil de desenvolver seu programa sem ter que inserir ou remover o microcontrolador. Você apenas desenvolve o se programa e baixa ele direto para o microcontrolador pela própria placa de teste. Esta placa utiliza a porta paralela do computador e suporta PIC16F, PIC18F de 40 pinos.&amp;nbsp;&lt;/div&gt;

Lego Mindstoms, o Lego todos já devem conhecer, e o Mindstorms ? O mindstorms é a ideia do Lego associada a robótica, o Kit possui uma grande quantidade de peças que se encaixam umas nas outras, &lt;br /&gt;
engrenagens, servomotores, sensores e o mais importante, a unidade lógica programável, e o que se pode fazer com ele? Sua criatividade é o limite, os entusiastas da mecatrônica ou apenas hobbistas, podem pôr em prática quase qualquer robô que tiverem em mente.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Não sendo apenas um brinquedo mas uma ferramenta de apoio a criação, inúmeras escolas que lidam com algum incentivo a tecnologia em sua grade, possuem aulas em que introduzem as crianças ao contato com o Mindstorms para despertar-lhes a criatividade.&lt;br /&gt;

&lt;br /&gt;
O Codewarrior, para quem não conhece, é o software de desenvovimento para gravação de microcontroladores da Freescale, não é gratuito mas possui versão trial para testagem com algumas limitações.&lt;br /&gt;
&lt;br /&gt;
É um software um pouco pesado, portanto os PCs mais antigos podem ter problemas de rodar &quot;meio travando&quot; ou nem rodar, mas a funcionalidade compensa pois ele é muito completo.&lt;/div&gt;

Freescale semicondutores que antes pertencia a motorola tem se destacado no mercado de microcontroladores, quando se fala em microcontroladores a primeira referência que vem a cabeça é PIC, se você está iniciando na programação de microcontrolador também deve começar com o PIC, pois é de fácil acesso, toda loja de eletrônicos tem, para gravar, você mesmo monta o gravador, tem vários projetos pela internet sobre gravadores de PIC. Mas em comparação com um Freescale a capacidade de um PIC é bem pequena, o mesmo para o preço, o Freescale sai muito mais em conta, mas só vendem por quantidade mínima, e um gravador de Freescale vai te custar por volta de mil reais, porém se você já possui uma empresa pequena ou média, ou se trabalha para uma e quer experimentar novos equipamentos, pense nisso, essa empresa está crescendo muito na área de novas tecnologias, se você ainda não conhece ainda, provavelmente vai se deparar com eles no futuro.&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
Assembly é a linguagem das máquinas, é indicada pelos especialistas como a melhor linguagem para programar microcontroladores sem o risco de criar bugs desnecessários, pois cada passo do microcontrolador tem que ser descrito 1 por 1, também indicada&lt;b&gt; &lt;/b&gt;por professores de cursos ligados a área de tecnologia para ser a primeira linguagem a se aprender a programar microcontroladores, pois aprendendo primeiro e migrando depois para outras linguagens estará mais apto, ao se aprender assembly exige que se aprenda muito mais sobre a máquina em sí.&amp;nbsp;&lt;/div&gt;
