Descrizione
hi guys, I have this relay: im trying to connect it this way: (althoug the next image is a 5V relay im using the 12V one, it waas easy to find the image of the 5V but my relay is the 12V one) If I connect the DC+ and DC- to the arduino directly, the green light of pwer from the relay turn on, and with the blink program the red light of the relay is turning off and on and the blink in the arduino is also working(i added the blink in both arduino and relay ti see what happens), so the sign
