21 Band Audio Spectrum Analyzer

This is a project I came across from Hackady.io from Samm928, All credit goes to him! Just thought it was a really nice project and I have seen some of these boards completed selling for over $100. So, when I seen this project using inexpensive modules, I had to give it a try! PCBway boards are sweet as usual :) Thank you again
