通过单片机控制电机模拟电梯自动升降，02./*项目名称：基于51单片机的自动升降电梯简易模型

03./*主控芯片：STC89C52

04./*使用模块：28BYJ_48步进电机、ULN2003驱动模块、无源蜂鸣器、红外发射器、红外接收头、4×4软键盘

05./*平台搭建：废旧泡沫块、硬纸壳

06./*主要功能：装置供电后，通过按下红外遥控器或者软键盘选择楼层所对应的数字，选择升降方式（只上升、只下降、先升再降）

07./*　　　　　然后升降电梯（泡沫模拟）停在对应楼层，蜂鸣器发出“叮咚”的声响。共计16层。

08./*引脚说明：步进电机接P1低四位，蜂鸣器IO口接P3^7，红外接收头接P3^2，软键盘接P2口；(MCU　 02. / * project name: automatic elevator simplified model based on 51 single chip microcomputer
