Home automation project IR Blaster - Node-Red based IR sender for your smarthome

IR-Blaster

The IR Blaster is a simple IR sender module with an onbloard ESP8266 microcontroller board. You can controll RGB LED stripes or a TV with the IR Blaster and a smartphone or tablet.

This smartphone project is published in my Book "Heimautomation mit Arduino, ESP8266 und Raspberry Pi, ISBN: 9783958456716" https://www.mitp.de/IT-WEB/Elektronik-Maker/Heimautomation-mit-Arduino-ESP8266-und-Raspberry-Pi.html
