Relay board LED lights but it doesn't switch

Q&A Forum › Category: ESP32 › Relay board LED lights but it doesn't switch

Hello, I used the ‘ESP32 Websockets control multiple outputs’ tutorial. I am trying to control a relay board.
When I touch the toggle switches on my computer, the LEDs on the relay board respond, but it does not click.
I am now getting Vcc of the relay board from Vin of esp32. And when I measure, there is 5.1 VDC.

Where could the problem be?

Thank you

Hi.
If the LEDs of the relay are working, it means everything is working properly, except some wiring or configuration on your relay. What relay module are you using? Can you send a link to a picture?
