So I recently bought a 12v 2 channel relay (well 4 of them actually) for a little project of mine. Iv'e hooked the relay up in the way I believe should work but unfortunately no LEDs are lighting up. Below is a picture of the relay I am using.
So basically I have one 12v power supply. I have attached the negative wire to the gnd pin and then the positive to vcc, in1 and in2 (all circled in red) so that basically when 12v is supplied it should trigger both relays. So is my relay broken or is my wiring theory just completely wrong?
Thanks in advanced!
