AVR IR Remote Control System

An infrared (IR) link that provides bi-directional communication between the NXT and the new Power-Functions system, which consists of a battery box, motors, a remote control (an IR transmitter) and an IR receiver that controls the motors.
Sivan Toledo says: I previously built an IR transmitter for the NXT which used an MSP430 microcontroller and which was able to send Sony IR commands (the specifications of this protocol are widely available). So why the need for a new IR transmitter ? Well Sivan wanted to achieve a couple of new goals:

* To analyse the Power-Functions IR protocol, for which no documentation is publicly available.
* To build a system that could not only send IR commands, but could also receive and decode them.
* To experiment with AVR’s, another family of microcontrollers.
