Do you a vivid game player that has a familiar experience with the “Slaying Dragons” game? Well, if you did, then you’ll be very interested about this infrared IR link project!

You must be wondered, “What’s the specialty about this infrared IR link?” For your information, this infrared IR link is provides bi-directional communication between the NXT and the new Power-Functions system. Those components that consist in this infrared IR link are a battery box, motors, a remote control (an IR transmitter) and an IR receiver that can be used to control the motors!

You will need to use an AVR Dragon to program the ATmega88. The Dragon is a USB programmer or debugger. It can use to program the AVR by using several different protocols, and it can be used to conduct in-system debugging of an AVR. Normally, it costs less than $50 and it’s equipped with many great features inside it! The only matter about this AVR Dragon is it turns out to be a very sensitive device, and you should be watch out for its sensitive parts.

Hope you all will have fun with this infrared IR link and it’s time to slay the dragon!
