Entertainment System Remote

Extend the Rails server from the Chapter 7, Web-Enabled Light Switch project to transmit IR commands through a serial port connected to an Arduino that is attached to an IR LED.[115] Build the Arduino-assisted IR transmitter using Maik Schmidt’s instructions in Arduino: A Quick Start Guide [Sch11]. Place IR LEDs in front of all your IR-controlled entertainment center devices, such as televisions and audio receivers. Create a friendly user interface for your native iOS or Android client, or combine the IR user interface with other project client interfaces, such as the one we made for the Chapter 9, Android Door Lock.
