Traditional remote control with a dedicated encoding and decoding integrated circuit chip, this circuit, although the production is simple, but for a number of key capabilities may be limited, which can only be used for a particular electrical equipment, and thus its scope of application has been greatly restrictions. Using the remote control system of the singlechip design, with a flexible programming, and operation code number can be set, etc. This design uses AT89C52 as the main chip, decoding and execution of remote operation responsible for the infrared data。 28BYJ48 stepper motor is the final manipulation of the infrared signal object, using the remote control to launch different values of the stepper motor speed control.
