Dot Matrix Project : Fancy Leds

alfien1985@gmail.com — Thu, 07 Jan 2010 03:04:00 PST

The idea of this project came from Olivier de Broqueville's son. He was dreaming of a small tool able to write symbols or pictures on a screen. If using a graphic LCD, it was too expensive (or too easy?), so the solution adopted was to pilot a dot matrix of Leds. The Dot matrix project need only some cheap transistors, common red Leds, and a PIC microcontroller 16F628. And the dream could become

Electronic Project : AVR Lux Meter

alfien1985@gmail.com — Wed, 06 Jan 2010 03:16:00 PST

The illumination is how the level of flows of light falling on a surface. . The flow of light is visible, which is defined in the flow (the light power) divided by relative sensitivity of the naked eye on the visible spectrum. This means that the Lux is well suited to the light level of meaning to the human eye. To measure the lighting, we can use Lux Meter.We can build ourselves Lux meter using

Did you know that The human heart can be measured optically. The heart beat with the varying blood pressure leads to a measurable change in the visual content of peripheral blood vessels. This is as good at the finger detect. There are two project work available, which were so far advanced that the optical signal pulse seized on a liquid crystal display graphically. Both works have been with a

LCD SWR Meter using PIC 16F88

alfien1985@gmail.com — Fri, 25 Dec 2009 03:22:00 PST
