 | | Handy expansion board info?
|
|
Does anyone have a disused Handyboard expansion interface? I've been asked if I could update my C libraries to include support for it but I'd rather not buy one a full price just for that :-) --Chuck (URL) (23 years ago, 19-Mar-01, to lugnet.robotics.handyboard)

Fred- We unloaded the last three files that you mentioned, sonar.c, robot221.c, and gp2d02_i.icb, and then tested the Lego Shaft Encoder. This eliminated the problem we were having so we then loaded the files individually and tested. We narrowed the (...) (23 years ago, 14-Mar-01, to lugnet.robotics.handyboard)

Yes, it can be used to control a drill motor, but probably not directly. It can drive 9V motors at 1 AMP (i think, depending on which h-bridge chips you have). I'm sure a drill motor will draw more than 1 amp, so you will need to use external power (...) (23 years ago, 7-Mar-01, to lugnet.robotics.handyboard)
