I have successfully built and uploaded my program to the 50$ robot microcontroller. I have verified the program, but it still doesn't work correctly. The servos only spin in one direction.
At first I thought that the photo resistors were damaged, so I replaced and re-soldered them. This did nothing to help. The only thing that happens when I put on power to the board and servos is a continuous rotation. There is no reversal in direction nor any response at all to light or dark.
Now I think it could be my servos. I had them modified by Servocity.com to rotate continuously, instead of doing it myself (I'm lazy
). They have a little switch on the outside that reverses direction. Could this have something to do with it? Is there a different pulse signal for this to work?
Thanks,
Orrin
EDIT: The servos also rotate quite slowly.
