Wohoo! I received my package from Sparkfun today. It was packed with no less than three Arduinos (mega, pro 328 and pro mini 328) as well as an Arduino shield, 6-degree gyro parts and a MaxSonar ultrasonic range finder.
I've coded and scripted in quite a few languages up through the years, but I have never done anything with micro-controllers so I'm definitely jumping into the deep end with this. Should be fun :)
