This post continues the series of simple Arduino applications written in C instead of the official Arduino language and IDE. See the previous posts about the basics, using a buzzer and a LED matrix. The goals of using C are mainly to understand better the microcontroller, to reduce the needed resources in terms of code memory, RAM and […]

This post is part of a series about programming Arduino applications in C. I’m going to show the results first, […]
