Control a BRIO train with your cell phone #MicroPython @lemariva

Mauro Riva blogs about automating a toy BRIO train using an ESP32 based microcontroller board. Programming is done in MicroPython.

This tutorial helps you update a BRIO locomotive using an ESP32 that runs MicroPython. As a result, you can control the speed of the BRIO using a cell phone or a laptop (basically, everything that has a browser).

If you don’t know what a BRIO locomotive is, check out the following picture:

BRIO World 33594
Fig. 1: BRIO World 33594

In this tutorial, I will try to accomplish the following points:

  1. Hardware modifications on a ESP32 board;
  2. MicroPython installation;
  3. Controlling the locomotive speed using a web browser.

See the tutorial here and a video of the project below.
