How to control DC motor off and on cycles.
I need to control the speed at which a pager motor is on or off. I don't need to control the motor speed, just the timing of off and on. What would be the easiest way to accomplish this? (I have some 555 timers and an Arduino Uno so either of these would be preferred methods).
I've tried but failed with the 555 timer and a pot to do this. Eventually I would like to have two pager motors cycling between off and on (pulsating effect).
