I've been building this PCB based on Muffsy relay input selector. I had added some optionals such as IR receiver, switch encoder, motorized potentiometer, LCD screen and an ethernet module (just in case). I replaced the NodeMCU for an arduino nano since it doesn't have build in wifi to interfere with internal components since im placing this with a preamp+amp and it has more available pins.

Question! I am looking to something similar, I want to add an LCD to show what input is selected. Would you happen to have the code on github for how you added your LCD?
