I am in the process of programming an Uno board to use capacitive touch sensors in my truck to toggle power to auxiliary relays. I pretty much have the coding down, just a little additional tweaking for that, and the coding is not the basis of my post.
I will be using the Arduino to control 5 separate relays and want to make sure i have the wiring down so that I do not fry something in the Arduino or my truck. Attached is a diagram of the intended wiring setup, but I wanted to make sure I have things run correctly to keep common grounds and correct component placement.
Any input would be greatly appreciated.
