Newbe here. Don't know jack about electronics, but I have a deep desire to learn about them.
Working on a project that has two 12v dc vibrator motors, each independently controlled with PWM controller to create a Interference pulsator modulation between the two vibrators, similar to a Nobra Twincharger.
I would like to add a master control potentiometer to control the two PWM controllers so that once I get the proper frequency interference of each motor, I can then use the master pot to increase or decrease the amplitude of both units. Clear? Probably not. Here's a diagram:
