The buzzer is a simple electromechanical device that produces sound when a voltage is applied to it. The ESP32 can control the buzzer’s on/off state and, by rapidly switching it on and off, generate different tones.
Control/Communication:
Controlled by the ESP32 using a digital signal.
Signal: Connected to a GPIO pin on the ESP32 (e.g., GPIO 11).
GND:Connected to GND.
