H-Bridge

nelson1000

first off I would like to say Hi to everyone! I am a begginer to robotics and am wanting to get my stamp to control two DC motors. I bought the BOE-BOT kit about 6 months ago and am now in the process of designing my own bot. Anyways I have serched and could not seem to find much info. The motors that I want to use are going to need between 6-9 volts and I was wondering where to start with the H-bridge.

Thanks for any help !!

If you're seeking independent control of the motors, and you're looking for a small, packaged solution, you can't do too much better that this, from MondoTronics (The Robot Store):

If you're sticking with a small bot and using the BASIC Stamp as its brains, this motor controller is very useful:

I'm a big fan of Pololu's Dual Serial Motor Controller.... I have used it on several robots with Basic Stamps and has worked flawlessly. The best part is, you can get it from Parallax!

The Monkey Head Hack (see EFX forum) is using the Pololu.
