“This circuit sets up the common 555 timer IC to output a PWM pulse that can be varied by the position of a connected potentiometer. PWM (pulse width modulation) is commonly used to control the speed of motors or brightness of LED’s. With just a few common electronic components this is one of the simplest PWM circuits you can make.”
