I ordered 5v relays but for some reason i got 24vdc relays, and i am not going to argue with them again, but i have a 6n138 opto isolator, and a bunch of npn 2n3904 treansistors, and the data sheet for the isolator is confusing me so would anybody be kind enouhgt to help me out with a schematic for h-bridge with this, its going to controll 1 small motor, 2 amps is be far enough. I am going to be using a 9.6 v nicd bettery for the motors and a 9v for the basic stamp 2. I also got a breadboard and alot of time, so any help would be very nice.

    If your relays do indeed require 24v to energize you will also need a source of 24v. what is the model number of the relay and where did you buy them?

    I don't know if this will be of any help but here is a link someone sent me about H-bridges: www.mcmanis.com/chuck/robotics/tutorial/h-bridge/index.htm
    Hope this helps you out.
