    Use NOR gates for PWM H-bridge driver while keep motor stopped

    Hi, I am trying to use the CD4001 NOR gate chip to control the DIR and PWM of a H-bridge so that the motor can run at variable speeds in either direction. I found a very good article about this discussing in detail how this can be done at lamja.com http://www.lamja.com/?p=58. While...
