Remotes have become our most natural means of controlling certain appliances, and if you're like us, you'll occasionally spend several minutes trying to locate a remote control rather than trying to engage some device's obscure front panel. In the future, we expect to see more appliances forfeiting the front panel altogether in favor of the keypad of a simple remote. Here's a rule of thumb: If you are building an appliance that might be enjoyed by people while they are sitting on a couch, include a remote control.

In this chapter we will cover the following topics:

  • Communicating with infrared light

  • Hardware for remote control receivers

  • Installing and configuring LIRC for the Laddie appliance
