| Fred, (et al) Actually I did test to make sure that the LCD was receiving the signal. And indeed it was. I did this before I posted and thought I made it clear. So I guess my problem should have been directed elsewehere since it is not entirely HB (...) (29 years ago, 22-Feb-96, to lugnet.robotics.handyboard)

| Is this OK for getting 6V to motors connected to the L293s? I tapped off the center of the battery back and get about 6V. I then soldered a wire at that point on the battery pack and then soldered the other end to pin 8 (Vs) of each of the L293s (I (...) (29 years ago, 20-Feb-96, to lugnet.robotics.handyboard)
