Want to do it? Here is what you need to do
1. PCM Remote Control Systems Receiver Module, I choose VISHAY’s TSOP1738 which can sensitive to 36KHz Carrier Frequency and 950nm wave-length […]

// Include Standard files
#include “Board.h”

HI,

And here is AT91SAM7S32
 

Here is a picture of my recent buyed ATmega8 AVR, comparing to ATmega128, it is only a “small” device.
