智能窗帘设计：实现智能家居的便捷生活

AbstractWith the rapid development of technology, people's demands for their living standards, air environment, and living quality are getting higher and higher. Therefore, smart home systems have gradually entered our sight, mainly providing convenience for our lives and realizing our concept of a technology home, a smart home, and a green home. As a module in smart homes, the potential for the development of smart curtains is unlimited. In the hardware design part, I use the STC89C52 as the core of the design. I first outline the operational characteristics of the microcontroller and the use of its main pins. I introduce the crystal oscillator circuit, the role and connection diagram of the reset circuit, and the features of the DS1302 clock. I present an overview of its overall layout and connection diagram, the working principle and parameters of the stepper motor circuit, its structure diagram, the various functions and characteristics of the LCD1602 display, and the working principle of the TSL2561 sensor and its connection with the microcontroller. In the software design part, I introduce the operation flowchart of my main program module design, describe my own design concept, and present the operation flow of the stepper motor module, keypad module, manual control module, timing control module, and light-sensing control module. Finally, through debugging, I successfully implemented the functions of manual control, timing control, and light intensity-controlled curtain opening and closing in this graduation design.
