I am trying to build an automomus robot that will have IR LED's for obstacle avoidance. I am using a nice little gear box i bought and a nice tank track set (all from sparkfun) I need some help some links to some pics or anything to help me get these IR LED's wired up. I also need some help on the coding half of it. I have searched online for hours and all the info i can find talk about doing it without the adafruit motor shield.
