超声波测距(LCD1602显示）
超声波测距原理是通过超声波发射器向某一方向发射超声波,在发射时刻的同时开始计时,超声波在空气中传播时碰到障碍物就立即返回来,超声波接收器收到反射波就立即停止计时。(Ultrasonic ranging (LCD1602 display)
The ultrasonic ranging principle is ultrasonic transmitter in a direction to the ultrasonic transmitter, while the launch time of start time, ultrasonic wave propagation in the air when the obstacles to return immediately, the ultrasonic reflected wave received by the receiver immediately stop the clock.)
