Most consumer electronic devices come with a handheld remote control that allows you to wirelessly control the device from a short distance. Remote controls produce digitally encoded IR pulse streams for button-presses, such as Power, Volume, Channel, Temperature, and so on. However, can we extend the control distance between the device and the remote control? Yes we can; by using Arduino IoT in conjunction with a few electronic components. This chapter explains how you can incrementally build an Internet-controlled infrared remote control with Arduino.
In this chapter, we will cover the following topics:
How to build a simple infrared receiver and decode values for each remote control key
The infrared raw data format
How to build an infrared sender to send the captured raw data to the target device
How to control the infrared sender to interact with the target device through the Internet
