Reuse your old Arduino hardware while learning Python.

Snek [1] is a tiny embeddable language that can run on processors too small for MicroPython. It supports about 20 of the older Arduino modules (e.g., Duemilanove, LilyPad, Mega, Nano, and Uno), as well as Snekboard controllers and LEGO robotics projects that use the LEGO EV.

Snek is based on Python syntax, but it only supports a small subset of the full Python language. The Snek implementation on Arduino hardware allows you to build some enjoyable Python projects with just a few lines of code. The programming experience you gain in Snek can be used in larger Python 3 or MicroPython projects.

In this article, I introduce Snek by showing you how to install and set up some simple Arduino projects. None of these examples use more than 10 lines of code.
