Sensor Ne555 Pulse Width Modulation (PWM) Motor Speed Controller DIY Kit
At the heart of this kit is the legendary NE555 Timer IC. When assembled, the circuit operates as an astable multivibrator, generating a high-frequency square wave. By turning the included potentiometer, you vary the “Duty Cycle”—the ratio of time the signal is ‘on’ versus ‘off’—without changing the frequency.
