摘要
利用AT89C52单片机作为控制器,产生脉冲宽度调制(PWM)波形以控制直流电机的转速,进而控制震动的速度和幅度,实现对人体某部位的按摩.利用直流电机芯片L298N驱动12V直流电机,实现电机的正转、反转和多级调速,并在LED上显示按摩器的档位和正/反转情况.设计的智能按摩器的具有制作成本低、使用方便、功能多样等优点.
AT89C52 single chip microcomputer is used as massager controller which generates pulse width modulation waveform to control the dc motor speed and the vibration speed and amplitude so as to realize intelligent massage.The dc motor chip L298N is used to drive 12V dc motor to realize the forward and backward turning and multi-stage speed adjustment of the motor.The massager gear position and the forward and backward turning status are displayed on the LED.This intelligent massage device has the advantages of low production cost,convenient use and various functions.
