SMD components are electronic components that are designed to be mounted directly onto the surface of a printed circuit board (PCB). Unlike through-hole components, which have leads that are inserted ...

An SMD (Surface-Mount Device) LED is typically identified by its numerical code, which represents the dimensions of the LED package in millimeters. The code usually follows a format where the first ...

This is a fork of the code and examples from "Make: AVR Programming" that I've addapted to work with the Arduino Uno R3 (I'm using the SMD variant, but it shouldn't matter which UNO R3 you're using).
