    Hey Guys,

    Great little community you have here - glad to be a part of it...

    I'm basically trying to come up with a circuit that runs a DC 9volt motor, controlled by two momentary NO push switches for forward and reverse, with a potentiometer in the mix to be able to adjust the motor speed.

    I've scoured this website and the internet, but due to my COMPLETE lack of knowledge i'm unable to come up with a complete solution... i just don't quite understand it.

    I think a relay is needed, but i have NO idea what kind or how to wire it.

    What i've done is attached an image with the components to the system. If someone could PLEAAAASE take the image into paint or whatever and draw the wires in to where they go, and specify what type of relay i'll need (SPDT, DPDT, etc) that would be SO DANG HELPFUL. Thanks so much:rolleyes:

    If you're having trouble posting the image back into the thread you can email me as well...

    Look at the many circuits on this site that deal with PWM (pulse width modulation). One should run your motor just fine.
