Hello guys,
I have this relay Dropbox - File Deleted - Simplify your life . I am trying to turn on and off one led first and after move for some real 220VAC lights.
I am connecting GND to ground of the arduino, IN1 to some digital output of arduino(i am using also the transistor 2N2222) and the VCC to 5V of arduino. For the LED i connect the cathode to the ground and from 5V from arduino through the relay and after to the anode of the LED. I am using just some simple code for turning on and off the relay(delay 1sec). The only thing that happens is to blink one small light from the relay that i think show that is receiving the data. But the LED connected to output of the relay dont turn on. I am connecting the 5V to middle and right pin of K1(Dropbox - File Deleted - Simplify your life)
Do you have any idea why?
