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

When trying to upload to your board, you may get the following error:

Cannot perform port reset: 1200-bps touch: opening port at 1200bps: Permission denied No device found on ttyACM0

This is a serial port permissions issue. Add your user to the dialout group, rebuild your system, then log out and back in or reboot to apply:

{
  users.users.<myuser>.extraGroups = [ "dialout" ];
}

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
    ];
  }
) { }

Upload program

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.
