Turn your boring light switch into a functional PIN pad! This cover replaces your standard single-gang switch plate and houses a 4x3 matrix keypad, letting you trigger your Arduino with a secret code. Inspired by servo-based light switch automation projects, this takes it a step further with user-input control.This design was part of my "10 Interactive Switch Mods" series — check out all the variations and build guides over at PluggedIn3D: https://pluggedin3d.com/arduino-light-switch-mods/🔧 Required MaterialsELEGOO UNO R3 Starter Kit (includes breadboard, wires, resistors): Amazon affiliate link4x3 Keypad (2-pack): Amazon affiliate linkAs an Amazon Associate I earn from qualifying purchases.
