ESP32 with KY-038 sound sensor and buzzer

Postby LostMind » Tue Feb 13, 2024 6:27 pm

Hello everyone!

I want to build an alarm system. Where I use the KY-038 sound sensor and it sounds the buzzer. Unfortunately, I can't find a connection diagram with the ESP32 and KY-038 sound sensor anywhere. Can anyone help me how to connect it and with a simple code?

Thank you in advance for your help.
