Hi!
I am considering about making the $50 robot, but I am a little bit confused. I mean i saw the list of parts and I can't decide if I need the AVR STK Serial Port
Dongle Programmer, the AVR ISP2 Programmer and the Pocket AVR Programmer too, or I just need one of them. I am confused about the batteries too. I should buy all the 3 or just 1?
