Ringing a buzzer with PWM. This is an exercise to ringing a buzzer with PWM. The PWM stands for Pulse Width Modulation. The PWM is used for making digital waveform which has specific pulse width. The PWM module of W7500 chip embdded in WIZwiki board can makes various digital waveform. Using this PWM, user can make high or low tone sound, control LED brightness and control motor speeds. This is the circuit for this example.
