user77801: Trying to power the 12V relay from an Arduino to make an automatic cocktail maker.  Looking to power 12V water pumps off of the relay.  However, the relay is not clicking, only getting the light.
The connections FROM the Arduino TO the relay is as follows:




Arduino
Relay




5V
VCC


GND
GND


pin 3
IN1




Also pictures of circuit are provided. The Arduino is powered by USB laptop.




user77395: After search the internet,
i believe the 12v relay need 12v to click.
