Bitwhacker firmware oddities
When my bitwacker's 6 input pins are connected to a breadboard with light sensors, strangely only pins 1 and 6 are accurate. Pins 2-4 receive a signal, but flip in value when they reach a certain point. Also, RA/4 receives no signal at all. Ali thinks this has to do with the firmware on the bitwacker. Hopefully his friends at Berkeley will know how to fix this problem.
