Hello I am just wondering what would be needed to complete the following.
I need an arduino to output 12v through the green / purple wires.
The up down button will be virtual button on a touch screen. So basically I just need 2 12v outputs from arduino. When pressing up on screen it supplies 12v to green. When pressing down it supplies 12v to purple. Should be fairly simple.
Correct me if I am wrong.
So aside from the main arduino (such as uno), and coding what would I need to output 12v signals?
