Arduino

The Arduino ecosystem offers two Versions of the Arduino IDE and an Arduino CLI that both base on. The latter can be used for building Arduino projects with nix.

Arduino IDE 2.x

The Arduino IDE 2.x is available in nixpkgs as arduino-ide

Arduino IDE 1.x

This is the old Arduino IDE and it is available as arduino in nixpkgs. It is still used for many projects.

shell.nix

{
  pkgs ? import <nixpkgs> { },
}:
pkgs.callPackage (
  {
    mkShell,
    arduino,
  }:
  mkShell {
    strictDeps = true;
    nativeBuildInputs = [
      arduino
    ];
  }
) { }

Arduino CLI

The Arduino CLI is available as arduino-cli in nixpkgs.

Build Arduino project with Nix

Ardunio-Nix allows generating all dependencies from an Arduino project as Nix dependencies. The Arduino-Env patch makes it possible to build these Arduino project within Nix.
