Hello!

I got this 5 V Relay Module but I do not have any manual or clue where to connect it?
Digital outputs? Which pins would be the best?

All info are welceme! Thanks in advance!

You can use any of the digital outputs, use/define the same pin in the sketch to operate the relay. Good Luck!!!

Thanks, Luck is just what I need, ha haa :slight_smile:

On this relay module three pins are marked S, + an -. Any knowledge of what these are?
S = signal ?

  • = Vcc
  • = GND

Am I right? Any suggestions?

Yes, you are right. S is where you will connect your digital output. Also you can refer link for more knowledge on relays Arduino Playground - InterfacingWithHardware
