Hi All, Most of you guys seem to want more power to control motors, well, I want to go the other way. I'm looking to drive 1.5v motors with the handyboard. The lowest voltage the L293 can take is 4.5v (Vmin of Vcc1), and that still has my motors (...) (26 years ago, 18-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 (...) (26 years ago, 18-Oct-99, to lugnet.robotics.handyboard)
