Scaled down BTTF Plutonium Gauge

My scaled down BTTF Plutonium Gauge for my 91 S10 shelf

The two meters on the left show random positions
The right meter tries to measure sound in the truck and display a value, a red led will turn on when it falls below 11
I had AI help me with the code, it prob can be tweaked better :)

I am providing the PDF for the labels I drew, printed on adhesive vinyl and laminated and stuck on to each meter face
