The issue is the use of low-cost series of MCS-51 MCU of the remote control with high reliability system applications. The design control through the realization of single-chip infrared communication, and thus charged with infrared remote control goals. MCU-based infrared remote control system and strong anti-interference, low power consumption, low cost, easy to achieve, with high practical value.
The design is HS0038 control infrared receiver to receive and process signals to single-chip AT89S52 as a signal detection and control of the core. Pulse can be achieved through the distribution of single-chip, thus driving thyristor control and by the high-power DC motor drive circuit 74LS14 and ULN2003 stepper motor consisting of (the) driver, combined with software to control the motor speed, steering. Used as LCD1602 LCD interface, can display DC motor and stepper motor, and speed, keyboard and remote control through a combination of setting the motor speed, the direction of the equivalent, will enable the system from the PC in the case of machines can also run the normal , has a good interactive features, improved system availability.The process uses assemble language, with blocking design and more readability and it’s easy to carry out vary settings by PC.
