In this article we wire an INA219 power monitor to an ESP32-C3 Super Mini, charge an 18650 cell through a TP4056, and serve a live voltage/current/power dashboard directly from the device using Microdot.
A €10 ESP32 touchscreen, a free F1 timing API, and a architecture problem that turns a Sunday afternoon project into something worth writing about. Here's how to build a live F1 pit wall display, and why the hard part has nothing to do with the hardware.
Build a Wi-Fi temperature and humidity sensor using the ESP32-C3 SuperMini, a DHT11, and MicroPython, and view live readings through a simple built-in web server.
In this article, we build a captive portal on the ESP32 using MicroPython, allowing users to configure Wi-Fi through a simple browser-based setup page.
In this article, I’ll show you how to set up an ESP32-C3, flash MicroPython, and write your first program; all while keeping things simple, practical, and beginner-friendly.
