Hi,
So my friend and I recently got the Make:it Robotics Starter Kit, and we put together the walking version; we're pretty sure everything is put together right, and the code uploaded to the Uno with no errors, but it isn't working. The motor on one side turns continually (It's supposed to alternate with the other side) and the one on the other side never activates at all. We tested that motor in the spots for the one that works, and the motor itself is working fine.
Theoretically the tape on the legs going past the light sensors is supposed to tell the motors when to start and stop, and we noticed that the way the legs are set up it never really goes in front of the sensor on the one that works. On the other hand, changing the placement of the sensor so that it does didn't make any difference.
The code we're using is here: http://blog.radioshack.com/2014/05/radioshack-make-magazine-launch-make-robotics/
I'm curious if anyone has had the same problems, or knows anything we might have missed. Thanks!
