In this hands-on project, you’ll learn how to control devices remotely using an ESP32 board, a relay, MicroPython, and tunneling software. We’ll guide you through setting up the hardware with a breadboard and relay module, installing the Thonny IDE, flashing MicroPython firmware, and running a web server on the ESP32 to control devices via your local network. You’ll also set up ngrok for secure remote access from anywhere. By the end, you’ll have a fully functional web-controlled relay switch, with code available for download. All steps are done in a Windows 11 environment but can be adapted to other systems.
