Hello to everyone,
I am a newbee in electronics and I am trying to control some lights using a 4 socket relay Board and an arduino uno. I have "gutted" an old power bar in order to get the electronics into it. What I would like to do is to have leds over each socket turning on when the circuit is active. I have some surface mounted mini leds on the relay board. My question: Can I just connect the new leds using the mini leds (parallel - like when using the blinky sketch and an external Led on the arduino 13 pin...)? If yes will I need a resistor? If not how do I do it?
Thank you very much for your time.
