Afterwards the microcontroller listens for an echo.
The time from transmission to echo reception lets you calculate the distance from the object.
The project uses 5 standard transistors to receive and transmit the ultrasound.
It also used a comparator to set the threshold echo detection level.
The ultrasonic transducers are standard 40kHz types.

Project 2 - A PIC video superimposer

noreply@blogger.com (nano) — Wed, 15 Oct 2008 01:27:00 +0000

This project is designed to show how to build time-dependent applications on PICs in C and to deal with restricted hardware.
It will also help you to have a start point, if you need a simple way to add text to a PAL composite video signal in real time.
With only an 8 pins PIC and a few cheap components, you can superimpose constant or dynamic text to a composite video PAL signal.
To superimpose text to a PAL video signal, we need to control timing with precision to get a stable picture.
We have to deal with vertical synchronization, which tell us when a new frame starts, and with horizontal synchronization, which tell us when a new line starts.
External circuit is used to extract both vertical and horizontal synchronization pulses from the PAL video signal.
The LM1881 integrated circuit does it very well for example.
