Simple and yet fun to make arduino bot. Just follows the strongest light source. Using two LDRs, a modified pico and 1xAA and 2xAA battery packs, to give out 4,5 volts. Just enough to power theSN754410 and motors. But it gets around.
Had a little accident, it drove over a carpet, or it came about 30cm into it and some funny gear-whining noise came :P
A lot of hair in the gearbox, had to take it apart and clean it.
Future plans:
* Crash sensor, a small micro switch in front.
* Speaker, plays sound according to light source :P
* Better code
* Low voltage alarm
More stuff to come!
