2 min | 3191As you may have noticed in my past videos, I've been using a self-made rotating platform to display the projects. In this article, I'll describe and present it to you. It is still in its baby step, and I need a case to put everything inside. However, the code is available. The microcontroller is an ESP32, which is connected to Wi-Fi and hosts a website to configure the angle, speed, and direction of rotation. The ESP32 is programmed using MicroPython. Check out the following video!...

2 min | 1681I've just updated the LoRa/LoRaWAN repository for MicroPython and added a configuration that works on the M5Stack Fire using the LoRa868 Module. Therefore, this will help you connect the M5Stack Fire to the "The Things Network (TTN)"!
If you're new to MicroPython read this tutorial: Tutorial: Getting Started with MicroPython on ESP32, M5Stack, and ESP8266If you want to know more about the LoRaWAN and MicroPython, read this article: Tutorial: ESP32 running MicroPython sends data o...

6 min | 2863Spring in Europe has already started, and many people are having allergy problems. Therefore, I thought of making a project to measure air quality and collect this data to train a model that can tell me, when is the best time to open my apartment windows to let some fresh air into the apartment and thus minimize possible allergy attacks and sneezing! Like almost everyone right now (thanks to COVID-19), I'm working from home and this beautiful...

This tutorial is about programming the M5Stack Atom using MicroPython to transfer data to a LoRaWAN gateway. The gateway is then connected to the "The Things Network" (TTN) to process the data.
Before you start reading, check out the video of this setup!
The M5Stack ATOM Matrix is the most compact development board in the M5Stack development kit series with a size of only 24 x 24 x 14 mm and a weight of 14 g.
It has:
- 6 GPIO (Dupont Pins)
- GROVE/4Pin PH2.0 interface
- 5 x ...

MicroPython has almost all the features of Python, and allows you to easily interact with microcontrollers and sensors, making them accessible to both beginners and experienced Python programmers.
If you are new to MicroPython, I quote the official MicroPython page for you:
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on microcontrollers and in "constrai...

4 min | 7058This is a tutorial to control and display widgets on an E-INK display using an ESP32. Three widgets are available:
- Weather: weather forecast obtained using the OpenWeatherMap API.
- News: news highlights obtained using the NewsApi API.
- Notes: notes that can be added using a web-server that runs on the ESP32.
The result can be seen in this video:
Thus, in this tutorial, I will try to achieve the following:
- A guide to compile MicroPython to freeze modules;
- A setup guide for ...

The MicroPython official version doesn't support I2S interface. However, tsaarni wrote a driver for the OV2640 and forked the MicroPython repository to include it. Thus, you need to follow the instructions in this article: MicroPyt...

LoRa is a wireless data communication technology that enables you to transmit data over a very-long-range (more than 10 km in rural areas) with low power consumption. It uses license-free sub-gigahertz radio frequency bands as the 169 MHz, 433 MHz, 868 MHz for Europe, and 915 MHz for North America.
In October 2018, I published an article about LoRa and ESP32, and I uploaded a project to GitHub. The project includes a SX127x driver for ESP32 running MicroPython. However...

6 min | 17702The M5Stack is a modular open-source toolkit for developing IoT applications. It is based on an ESP32, which is the core module and there are a lot of stackable modules that you can use for different projects. This enables to do rapid and high-quality prototyping!
You can program the core device using the ESP-IDF framework, the Arduino-IDE, Blockly or MicroPython. Unfortunately, the BLE is still not available using the official M5Stack MicroPython firmware (forked from LoBo). Howeve...
