Based on the above discussion, the document titled "Design of an MCU-based intelligent home curtain control circuit - Graduation Thesis.doc" describes the design of an intelligent home curtain control circuit. The circuit is capable of manual control, timed control, and light control. However, remote control function has not been implemented. The document begins by introducing the basic knowledge and application prospects of smart homes. It then focuses on the hardware structure and principles of the integrated chips used in the development of the MCU-controlled infrared remote control curtain system, including the STC89C52 microcontroller, L7805 voltage regulator chip, LCD1602 LCD display, DS1302 clock chip, AT24C02 storage chip, 28BYJ_48 stepper motor, and HS0038 infrared receiver circuit. The document analyzes the hardware circuit design of the entire system, providing a system schematic diagram, power circuit, display circuit, DS1302 clock circuit, external storage circuit, motor control circuit, and infrared receiver circuit, along with relevant explanations for each circuit design. The software programming follows a modular approach, with separate programs for the LCD1602 display, DS1302 clock chip control, time adjustment and timing, stepper motor control, HS0038 infrared decoding, AT24C02 control, and light control. Each module is accompanied by a block diagram for easy understanding. Finally, through simulation debugging, the design of the clock, manual switch curtain control, and other controls has achieved the desired results. However, the system still needs continuous improvement and refinement in some design details. The key components used in the design include the STC89C52RC microcontroller, DS1302 clock chip, infrared remote control, LCD1602 display, and curtain.
