Hi,
I have a 555 that outputs a 12 volt PWM signal (call it source). How can I trigger another one-shot 555 (call it slave) that will go HIGH when the source is HIGH ( following the PWM signal ) , but shorten (or lenghten) the length of the pulse that slave 555 outputs???
The purpose is to relatively accurately match the speed of 2 dc motors that must spin at the same (low) speed.
Each 555 drives a MOSFET that powers each motor.
Any ideas?
Thanks
Denise
