This is a project circuit for infrared remote control with 3 output relay and easy to build. This circuit has 3 channel. This is the figure of the transmitter and the receiver circuit.
This remote control circuit is control by microcontroller PIC12F629 at 4MHz crystal for the transmitter and receiver. The transmitter use sleep mode for saving battery power, Use Phillips RC5 protocol, distance more than 7 m, this circuit is easy circuit to build and assembly and small amount of components. Uses RC5 protocol which is probably the most used by hobbyists, probably because the wide availability of cheap remote controls and easy to understand.
