Relay Doesn't Click. And a flyback diode is. A transistor is required to switch a higher current to the relay coil. Trying to power the 12v relay from an arduino to make an automatic cocktail maker. Excessive levels of current or voltage. An arduino output cannot drive a relay. Assuming it's like my relays, that relay can either power the relay coils and the logic inputs, or (if you remove the jumper) use. Here's a drawing for a board similar to yours, relay is energized on a low output. If the coil of the relay doesn't click, but the signaling led lights up, then vcc is not connected. Looking to power 12v water pumps off of the relay. It turns on but doesn't make the clicking noise. It opens and closes that switch, but doesn't provide power. Environmental factors such as temperature. Check if you plugged the wire really. You send a low voltage to the pin that controls that relay input and it closes the circuit,. When i directly connect the relay coil to 5v and gnd it makes the clicking noise.

Ac doesnt work when i replace the relay it clicks on and off u can here

Relay Doesn't Click Trying to power the 12v relay from an arduino to make an automatic cocktail maker. A transistor is required to switch a higher current to the relay coil. An arduino output cannot drive a relay. Some of the most common reasons why relays fail are: Looking to power 12v water pumps off of the relay. We will now take a look at some of the common failure modes of relays in more detail. Here's a drawing for a board similar to yours, relay is energized on a low output. It opens and closes that switch, but doesn't provide power. When i directly connect the relay coil to 5v and gnd it makes the clicking noise. Check if you plugged the wire really.
