Home | ESP8266


The ESP8266 is a module that adds a WiFi connection to your Arduino projects and more. This module is a true Arduino Killer. It has several GPIO. The most used models are the ESP-01, which has 2 GPIO (but not EC which is a shame) and ESP-12E model which features 12 GPIO (CE compliant). The ESP8266 can be programmed in Lua (language similar to Python) or using the Arduino IDE classic. For less than 2 euros you have a microcontroller with 2 GPIO with which you can make a small connected object (eg a connected button) without the need for an Arduino. In this category you will find everything you need to get started with the ESP8266: how to program in Lua or using the Arduino IDE, how to reinstall the original firmware, how to flash a custom firmware, the examples of assembly and codes …

Unpacking: shield SHT30 (temperature and humidity) for Wemos D1 Mini

shield sht30 wemos d1 mini shield battery oled

The DHT22 temperature and humidity sensor (and its small brother the DHT11) are ubiquitous in the Arduino / ESP8266 / Raspberry Pi tutorials. You are also probably familiar with Dallas DS18b20 which uses the 1-Wire protocol. Wemos offers a new expansion card, the Shield SHT30. The Sensirion SHT30 is a …
