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
