All the projects from the Arduino Projects Book, written in C.
Each project is separated into its own folder, with each folder having its own makefile. To run a particular project, clone the repo onto your machine, cd into the corresponding directory, run make to build the executable, and then flash the program onto your Arduino using the make flash command.
NOTE: Please double check which port your Arduino is located on using ls /dev/ | grep ACM then set the PORT variable in that project's Makefile to the output of that command.
In order to build and run these projects, you will need the following libraries installed on your machine: avr-binutils, avr-gcc, avrdude, and avr-libc.
As someone with an interest in computer engineering, low-level programming, and embedded systems, I'm using this project as an opportunity to work closer to the bare-metal of the Arduino Uno. This project was started in the hopes that it could be a stepping stone for me towards working with more professional/industry-grade boards (like the STM32 boards) in the future.
