- How to install Homie libraries on Arduino IDE
Reading time: 2 – 2 minutes
The second episode of ESP8266 programming series. In the next video I describe how to code a firmware for ESP8266 using Arduino IDE. The purpose of that firmware is create a temperature sensor and publish the reading in a MQTT broker.
Schema of the system:
Pictures of the system, I used ESP12E Devkit and some cheap parts:
References in Aliexpress where I bought the hardware:
Firmware source code is publishied in my github account: temperature sensor source code for ESP8266.
