There are 2 common drive methods. One is drove by PWM output port directly, the other is drove by the waves created by I/O regularly flipping level.
- PWM output port drive method: Drive the buzzer module with the square waves outputed by PWM output port. You just need to set specified period and duty cycle level valve on PWM port, so that to create the waves that comes with a frequence needed by the buzzer module to drive the module (need to works with audion).
- I/O flipping level drive method: A timer is needed. Uses the waves created by regularly flipping level to drive the buzzer module.
