/2/2017 the relay's led turns on, but with a tester I find out that the AC is coming correctly in, but never comes out from the relay! The led is on, but relay doesn't switch power.
Relay 4 Channel 24V relay Active High LOW Relay Module
So I am designing a simple project where my Arduino reads analog values from a potentiometer, or rotation sensor, as it is called on EBay, and uses that value to determine how many relays to close. I am connecting 4 digital pins to the relay module, and powering it with a constant digital signal from pin 2. Here is my code:
