asks for help to install stepper motor

Hi Ali

Have you supplied power to your break out board? I have just looked on Gary's site and the documentation for the BOB shows that an external power supply should be connected and unless I'm looking at the wrong one I cannot see any wires going to the power terminals.

you dont need to put an external 5V onto the BOB, you can just send the clock and direction from the bob to the driver, and as long as the clock and direction is close to the 5V, it will be fine.

All i need to know is if the clock and direction is coming from the PC and is high enough for the optos to operate.

Use 3 AA type (1.5V) batteries in series to get 4.5V and connect the negative end to the Pul- and tap the positive end on the pul +.
This will cause the motor to step one increment and while you may not see it moving, you will hear it.
You can also put some tape on the motor shaft so you can see the motion.
