Så här kopplar du Relämodul 5v för Arduino till en Arduino UNO eller ESP32, med ett exempelsketch som du kan ladda upp direkt.
This project demonstrates how to control a 5V relay module with an Arduino UNO. The sketch toggles the relay ON and OFF every two seconds while printing the status to the Serial Monitor. You will hear an audible click from the relay each time it switches state.
