无线遥控小车

随着电子技术的飞速发展，单片机与无线遥控已被广泛的应用到日常生活及工业中，成为测控技术现代化必不可少的重要工具。设计的无线遥控小车由四部分组成：主控模块、无线通信模块、电机驱动模块和电源模块。主控模块采用STC89C52单片机作为处理器；无线通信模块采用芯片PT2262和PT2272实现无线收发;用内置两个H桥的L298芯片驱动直流电机实现对小车的控制，实现前进、后退，左转、右转以及加速、减速的动作。整个无线遥控小车系统具有体积小、成本低、操作简单等优点，并具有一定的可扩展性。

Wireless remote control car

With the rapid development of electronic technology, microcontroller and wireless remote control has been widely applied in daily life and industry, and it has become an important tool to realize modernization of measurement and con- trol technology. The designed wireless remote control car has four parts, including master control module, wireless communi- cation module, motor driver module and power supply module. Master control module takes STC89C52 microcontroller as the processor, and wireless communication module with PT2262 and PT2272 chips realizes the wireless transceiver. L298 chip with two built-in H bridge circuits is used to drive DC motor, which controls the car, and realizes the forward, backward, left-turn, right-turn, acceleration and deceleration of the car. The wireless remote control car system has many advantages of small size, low cost, simple operation and so on, and it has a certain degree of scalability.
