This DC Motor Speed Controller is the perfect solution for adding a simple motor with adjustable speed to your projects. It emits a PWM (Pulse Width Modulated) signal that varies between 5% and 100% when the knob is turned. A PWM signal is a signal comprised of pulses that fluctuate between on and off. When the knob is turned all the way down, the signal is on 5% of the time and off 95% of the time, which makes your motor run slowly. When the knob is turned up, the amount of time the signal is on increases, thus speeding up your motor until the knob is turned all the way up and the signal is on 100% of the time. Popular for art installations, automation projects and anywhere else you may simply want to add something that spins with ease.
