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...
Last month, I published a review of the DSO138. This time, I put together the WAVE2 (15801K) and I review it in this article. The WAVE2 is a 2-channel portable oscilloscope design by JYETech for a hobbyist. It has a resistive touch screen display, X-T (signal-time) / X-Y (signal-signal) plotting functionalities, memory (4 blocks), measurement functionalities (V -max, min, avr, pp, rms-, frequency, duty cycle), serial interface and can be powered using an external 5V source (micro ...

This 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 ...

This tutorial extends the article MicroPython: Taking photos with an ESP32 and in this case, the ESP32-CAM running MicroPython takes a photo every 5 seconds and saves it on the microSD card. The photos can be then combined into a time-lapse video! :)
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...
The 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...
A few months ago, I was looking for a small digital signal oscilloscope (DSO) module, and last week I got a DSO138 DIY kit from DigitSpace. The oscilloscope is originally from the company JYE Tech, but as usual, there are a lot of copies.
The oscilloscope has a bandwidth of 200kHz, a maximum sampling rate of 1MHz and a maximum input voltage of 50Vpk that are sufficient for the applications that I am programming using ESP32 boards (more details here).
In this article, I include a qui...

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:
Fig. 1: BRIO World 33594
In this tutorial, I will try to accomplish the following points:

- Hardware modifications on a ESP32 board;
- MicroPython installation;
- Controlling the locomot...
