As we proceed through this chapter, we will take the example of a common TV remote control and learn how to hack into it and use it with an Arduino board. The general process of hacking into an existing remote control set has been explained in the following main sections:
- Using IR receiver TSOP Series IR receivers
- Building an Infrared transmitter device
We will use the knowledge in the following sections to receive the TV remote control's IR codes by using the IR receiver sketch. Later we will re-use the IR codes by transmitting them using the IR transmitter sketch and independently control the TV directly from the Arduino (without using the TV remote control). The same techniques can be used to read the IR codes of other remote control sets and also to transmit IR codes for controlling your own Arduino project remotely.
