1、单片机无线遥控小车毕业论文基于单片机AT89S51的无线遥控小车设计摘要近年来随着计算机在社会领域的渗透和大规模集成电路的发展,单片机的应用正在不断地走向深入,由于它具有功能强,体积小,功耗低,价格便宜,工作可靠,使用方便等特点,因此特别适合于与控制有关的系统,越来越广泛地应用于自动控制,智能化仪器,仪表,数据采集,军工产品以及家用电器等各个领域,单片机往往是作为一个核心部件来使用,在根据具体硬件结构,以及针对具体应用对象特点的软件结合,以作完善。该无线遥控小车采用玩具小车车架,。采用AT89S51单片机作为主控制核心,通过编码、解码集成芯片PT226
2、/PT2272无线传送操作指令,利用光电门分别精细检测小车左右驱动轮的速度,从而通过PWM动态调整、精确控制小车的速度与方向;该无线遥控小车的功能如下:在有障碍物的情况下实现20米内的无线遥控;实现前进、后退、加速、减速、左转、右转以及对速度档的选择。关键词:无线遥控单片机PWM无线数据采集ABSTRACTABSTRACTInrecentyearswithcomputerpenetrationinthesocialsphereandthedevelopmentoflarge-scaleintegratedcircuitsMCUapplicationsa
