After several articles to present the principles of MicroPython on ESP8266 and ESP32 development board, it's time to get down to business. I propose to take ...

The Arduino Uno or ESP8266 boards do not deliver enough power to power the 6 robotic arm servo motors discussed earlier in this article. So you have to buy a ...

ESP8266 + DHT22 + MQTT, here's how we will learn how to make our first connected object (a temperature probe) and connect it to the Home Assistant server. To ...

Last June, I introduced you to XOD, a new Open Source project for Arduino programming without Scratch's cousin block assembly programming. In a few months, the ...

In the previous two articles (unpacking the Wemos LoLin32 Lite under MicroPython and reinstalling the MicroPython firmware), we briefly discovered the ...

In many applications, ESP8266 WiFi modules can replace Arduino by adding Wi-Fi connectivity at a lower cost. At the launch of ESP8266 (in 2014), the preferred ...

If you want to create a temperature measurement network using an Arduino or ESP8266, the OneWire DS18B20 probes are ideal. The OneWire is a digital data bus ...
