I just hooked this up to my circuit and tested it out. I have 5 Volts running to positive and negative terminal pins and when I apply 5 volts to the in1 (labeled a bit oddly as IPP ON (InPut Port On maybe?) then I hear the coil flipping the switch inside with a nice click.
I have a separately powered circuit running about 2.3 volts with a 330ohm resistor and a small red led. That circuit runs through the NO (normally open) side so it is not lit until I input the 5v on the IPP. When I do, I hear the click and I see the red LED turn on.
It's just a test set up but this is one of my first projects and it is so cool I keep applying/removing the 5v very quickly and hear the nice switch clicking away inside the relay and seeing the red LED turn on and off very fast.
Lots of fun and a great little product. I will buy more from this company because the product works well and their shipping was great.
I used the same USB cable for power and signal, even though the USB only runs at 5v it was able to power and close the relay.
Your code may differ. For example, you may find that a digital pin and digitalWrite works for you. In any case the delays allow the circuit to stabilize and transients to dissipate between trip and close. The analog write 255 sets the voltage on pin 6 to +5V, and the analog write 0 command turns it off. You can hear the relay click on and off, and use a multimeter on the output lugs to confirm that it is working.
Relays need a diode across the input coil to prevent a bounce spike from ruining your Arduino when the relay shuts off. This little circuit has that, plus a handy LED to indicate a trip state, plus a circuit to match the current from the Arduino Uno, and for those reasons this is better than a bare relay.
