    I have a request, it's
    urgent, cause my undergrad project depends on it. (So,
    please reply fast). :(
    I am working on a project in robotics and my
    branch is Computer Science. I require a circuit idea
    for controlling a 12V, 500mA DC servo motor. I am
    reusing a receiver circuit of an RC toy car. Which
    provides me with two terminals with voltage varying
    between +4.5,0,-4.5 volts.( The two terminals provide
    positve voltage with respect to common ground)
    All I need is to drive the Servo motor, with direction control provided by the two terminals and common ground, without any
    form of speed control or braking. I am using a 12v
    lead acid battery for the servo and AA size batteries
    for the RC circuit. If you need any further
    information, please mail me on this address.

    Waiting for a reply,
    Regards,
    Ashish Narain

    NaviACE.

    P.S. I am not using any PWM signal, just driving the servo as any other DC motor (using it mainly for the high torque).
