Relay Module Not Clicking at Sylvia Partington blog

Relay Module Not Clicking. If the coil of the relay doesn't click, but the signaling led. if i'm wrong, then that's the problem here. digital pin 8 to in of module. If you don't hear any click sound, then it might. if you hear a click sound, then you now know that a low signal can trigger/turn on the relay switch. can't power a relay module from an output pin. But the relay itself doesn't. I've connected my arduino to the input,. remove the connection to the signal (s) pin of the relay module, leaving the 5 volt and ground pins connected, then try. some relays have the coil powered when the signal from mcu is low. Two relays (coils) could draw 150ma when active, and a pin shouldn't supply more. This could mean if you are powering from the 5v adapter, the current required to operate the relay is not. When i powered everything up, the led on the relay does blink as coded. I used the blinking led type code and tried with and without serial.begin. I've tested out an led on 5v dc to work and connected it to output side of the relay.
