Pete, It seems to me that a simple double pole double throw relay could be used to select one or the other module. That way you wouldn't need to tie up any other IC/OC pins. You fire one unit, get the return, then switch the relay and fire the other (...) (25 years ago, 19-Oct-99, to lugnet.robotics.handyboard)

Good point... There is another way. You can build your own h-bridges using mechanical relays and maybe a few diodes. They drop zero volts, which is good. However, you obviously can't PWM the things. If you just want rudimentary speed control, you (...) (25 years ago, 18-Oct-99, to lugnet.robotics.handyboard)
