The primary components of a practical infrared remote control system include: the infrared link (transmitter and receiver), microprocessor, and the interface components that allow the microprocessor to interact with the real world. This project involves the design and construction of an infrared transmitter and receiver linked to a microprocessor to control common household appliances i.e. lights, stereo, or coffee pot. The infrared transmitter sends 41KHz PCM pulses which are picked up by the infrared receiver connected to the 8751H microprocessor. The 8751H makes control decisions based on the transmitted code.
