ESP8266 and Infrared communication

In the previous chapters the ESP866 has been controlling relays, reading temperature and humidity, but not all the appliances around the house can be controlled with a relay. There are some of them that can be controlled using the infrared like TV or air-conditioning Now let's see how we can use ESP8266 to turn on/off a Panasonic TV. This can be extended to other TV brands by modifying the addresses and values.

Hardware components

To complete this project you will need:

ESP8266
Infrared LEDs (maybe from an old remote)
Some 100-ohm resistors (depending on the number of your infrared LEDs, one per LED)
One 1-Kilo Ohm resistor
One 2N2222 NPN transistor

Use the following schematic for the hardware part of this project:

Connect the output pin to the GPIO 12 from the ESP8266 the ground to the GND pin, and 5V to 5V from your ESP.

Software and libraries for this project

First let's install the library IRremoteESP8266. For that go to Sketch | Include Library | Manage Libraries...

Catalin Batrinu

Catalin Batrinu graduated from the Politehnica University of Bucharest in Electronics, Telecommunications, and Information Technology. He has been working as a software developer in telecommunications for the past 16 years. He has worked with old protocols and the latest network protocols and technologies, so he has experienced all transformations in the telecommunication industry. He has implemented many telecommunications protocols, from access adaptations and backbone switches to high-capacity, carrier-grade switches on various hardware platforms from Wintegra and Broadcom. Internet of Things came as a natural evolution for him and now he collaborates with different companies to construct the world of tomorrow that will make our life more comfortable and secure. Using the ESP8266, he has prototyped devices such as irrigation controllers, smart sockets, window shutters, Digital Addressable Lighting Controls, and environment controls, all of them controlled directly from a mobile application over the cloud. An MQTT broker with bridging and a WebSockets server was even developed for the ESP8266. Soon, all those devices will be part of our daily life, so we will all enjoy their functionality.
