Noobie electronics question:
I built the tristate circuit nuumio posted a while back and managed to get it working with my picaxe 28x project board. I then tried to use it with an 08pic and a little breakout board I had created for it however, I can't seem to get it working. The 08 pic has two 100k pulldown resistors connected after the outputs pins on output 1 and 2 which are then connected to 4.5v ground powering the pic. My tristate circuit uses 4AA batteries to power the motors, with the only input being the two pins from the pic.
