The IR obstacle detection modules on the AlphaBot were not working and the IR remote was also not working, so that was my project for the weekend.   One of the object detection modules wasn't functioning and the other one would function intermittently.  This is a simple circuit, so not much to check - ir diode, photo detector, pot, and comparator.     Turns out it was a silly assembly error on my part.  I neglected to use a nut as a spacer between the sensor board an ...
