Hi,
I'm pretty good at programming and not so good at electronics, sorry if my question is pretty trivial.
I want to control the 12V current off or on with Arduino without using a button to turn the 12V off and on, but is there any way other than using a relay to control the 12V off and on through Arduino?
simply like this, I have a lamp with 12V power and how to turn it on through the on and off button, and I want to make this automatic and controlled by Arduino.
