Hey all,
I want to use an Arduino (can output a maximum of 5VDC) to switch 120VAC lightbulbs. However, most 120VAC relays have turn-on voltages of around 30VDC. So what kind of circuitry can I use link the Arduino to the lightbulbs? Should I just use another relay in between the Arduino and the larger relay?
Thanks
