| Hi there, last week I've got my HB up and running and it works very fine. I've been playing around with it IC and some questions came up. I hope they are not too boring: - I don't know exactly in which manner sleep() works. It looks like being a mix (...) (29 years ago, 5-Feb-96, to lugnet.robotics.handyboard)

| Perhaps it would be best if first I could find a solution to this problem - What's the best way to drive 3V motors with the handy board? If I can solve this, I can really broaden my horizons as to the types of things I can use with the handy board. (29 years ago, 5-Feb-96, to lugnet.robotics.handyboard)

| (...) Be careful. Cheap RC cars tend to use 3v motors that want to draw a fair bit of current. Expensive RC cars use motors in a better voltage range for the HB (.e.g, 8.4 or 9.6v), but they draw serious current (5 to 10A easy). -F (29 years ago, 5-Feb-96, to lugnet.robotics.handyboard)

| (...) The problem with that solution is that the motors are driven bidirectionally - a regulator wouldn't work when the polarity it was given was reversed. (29 years ago, 4-Feb-96, to lugnet.robotics.handyboard)
