[Mr Muntarg]

I was hoping eventually to use a Bluetooth chip for communicating with the UNO so wouldn’t necessary have power from the usb , but I think for now till I’ve got it all working I’m going to park that idea . I removed the 12v plug on a previous project . I built a wind simulator for my sim racing rig . If I decided to use the 12v feed I’ll just solder wires directly to the board and save a little space 

What photosensors and lights are you using it’s the only part of the project I’m worried won’t work
