    Hi All,

    Does anyone know the circuit for run the 12VDC motor for 10 second and stop then run other direction for 10 second and stop. I am looking for circuit for both direction of motor and each direction run for 10 second.

    Thanks, for your help in advance.
    Kevin.

    Do you have DPDT 12V relays rated for ur motor current

    For the timing use a 555 timer or similar device wired as a monostable.

    Then you can use a H-bridge to control the motor.

    Remember you should allow time in-between switching the motor between one direction and another. Some H-bridges will not stop you from turning both directions on at the same time causing a short on the MOSFETs which usually leads to a release of the magic smoke or at best reduced efficiency.

    @ tom66.
    why I asked about relays is that OP might have more trouble using H bridges more than he could bargain for.
