摘要
以51单片机为基础,设计了一个声音导引系统.以声源和声音接收器确定小车位置,利用无线发送和接收装置来传送信号,由L298N构成的H桥来实现直流电机的正反转和调整转速,并用LCD1602液晶显示器显示小车速度,控制小车到达规定的目的地.
The paper designs a sound guide system based on 51 MCU.Using the acoustic source and the sound receiver definite car position,the signal is received and transmitted,bridge realizes the direct current machine by L298N the constitution H-bridge DC motor to reverse and the adjustment rotational speed,and with the LCD1602 liquid-crystal diplay demonstration car speed,control car reached the destination.
