Hi to all ! Am reopening this topic because i finally get the boards so i can test it directly.
Board:
Some schematics / not checked:
My question is how to connect this 12V relay board to raspberry. If i connect it like:
RSP----------RELAY
GND -------> GND VCC -------> 12V + from power adapter IN1 -------> GPIO raspberry
This setup is not working.
------------------------------------------------------
If i connect
RSP----------RELAY
GND -------> IN1 VCC -------> 12V + from power adapter GND -------> ?
red indicator light lights up on the side. So this should be confirmation that relay is triggered in low state ? If so, how should i connect all this together ? The problem is that i dont hear any relay click when the light turns on...
Any suggestion is welcome !
