This document describes using a Raspberry Pi connected to an infrared LED to build a new hardware block that can function as a universal remote control app running on a smartphone. The Raspberry Pi's GPIO pins would connect to an IR-LED to transmit infrared signals from a smartphone app to control devices like a DVD player or set-top box even when they are stored in cabinets.
