Hi there,
I'm building a robot, and am using a servo controller to control a bunch of servos. I'd also like to control the motors (via a h-bridge IC) with this servo controller.
I'm stuck on how to supply on/off to the h-bridge pins using the PWM signal of the servo controller. There is always a PWM signal (it's never off), so right now if i connect it directly the motor is always on.
Is there a way to "cut off" the PWM signal if it's below a certain theshold, and when not "cut off" it's a digital 1? It would be great if I can control motor speed, but a digital on/off would be fine as well.
Cheers,
Mike
