hello,
I am trying to make an arduino control a solid state relay which switches a 120vac load. I tried connecting a digital output pin and ground on the arduino to the the input terminals of the relay marked + and - without anything connected to the output terminals and the input status light was really dim. connecting the input terminals to a wall adapter works so I think I need a transistor. do you think this mosfet will work?
I always thought that transformers only work on AC but when I tried simulating a transformer on this circuit simulator, it seems to work with DC. why is that?
