“This is part one of a two-part project. For part one, we will focus on IR remotes and signaling, as well as IR reception and decoding. Using IR (InfraRed) radiation to control electronic devices is widely accepted and implemented. IR devices are routinely used in alarm systems, automatic door openers, and similar applications. This project makes use of coded IR emissions from a Sony TV remote, and a PICAXE microcontroller to manage the operation of a stepper motor. However, the same principles could be used for the control of AC or DC motors, relays, buzzers, lights, or almost any electrical or electro-mechanical device.”
