一个开发电梯模型用的小程序,基于AT89S51单片机,可以实现根据按键要求,电梯有厢体在不同的楼层停止.可以做为教学实验之用,程序已经测试过,楼层检测使用红外对管.电机使用三相步进电机.驱动使用LM298.-A development model with a small lift procedure, based on AT89S51 microcontroller, can be achieved under the key requirements of the lift with envelope in a different floor to stop. Can be used as a teaching experiment, the program has been tested, the floor of the tube using an infrared detection. Motor using the three-phase stepper motor. drive to use LM298.
