Hi
I have a small question.
ESP32-2432 has an audio amplifier. It is probably a complex area BUT all I want is to make a buzzer sound output.
Is there a simple way to send a square wave to the amplifier input?

Found the answer.
“pin 26 controlling the output of the amplifier” means it is outputting the signal on pin26 (see schematics of the device 8002A amplifier)
In it’s simplest form (blink sketch with the desired delay to choose the frequency)
