I'm completely new to raspberry pi so I'm sorry if this is a stupid question.
I have a raspberry pi and I connected two relays to it.
One of the relays works fine, the other doesn't, and it even looks like any pin I connect to the second relay stops working completely after I connect the relay.
I tested it with LEDs.. I made the LED turn on and off, but then when I replaced the LED with the relay, the pin stops working, even if I replace the relay back with the LED.
What am I doing wrong?
Here's a picture of the relay:
