    I've moved this post into its own thread. We like to start new threads for new topics here.

    For controlling your motor direction with transistors, try an internet search on the exact phrase "H Bridge."

    see the attached picture ... its valid if ur motor is DC

    To turn the motor in one direction the PWM signal is applied to the Va inputs, while the Vb inputs are held low. In this arrangement the positive voltage is
    at the left side of the motor. To reverse the direction the PWM signal is applied to the Vb inputs, while the Va inputs are held low
