Play music with an Arduino and a buzzer

Very simple code to play some simple music over a buzzer connected to an Arduino.

Usage

Hook up the buzzer on the pin specified in src/main.cpp and select which tune to play by calling it in the setup() function, then upload and enjoy!

Development

The code is compiled with PlatformIO but it should compile just fine with Arduino IDE as well, provided that you put the headers and source files in the right folders.

Build

pio run

Upload

pio run -t upload

LSP setup

To have clangd properly recognizing includes run

pio run -t compiledb

This will generate a compile_commands.json file which clangd can use to understand how each compilation unit should be compiled. Among other things it will also list the include paths pointing to the necessary libraries according to the target platform.
