1) 利用 Arduino 的数字引脚给超声波传感器的 Trig 引脚至少 10 微秒的高电平信号,这会让HC-SR04 超声波测距模块发射出8个40K赫兹的超声波脉冲(ultrasonic burst)。 2) 8个超声波脉冲发出后,echo引脚会输出高电平。假如没有声波返回,echo引脚会在38微秒后输出低电平。假如有声波返回,echo引脚会进
I have included 3 examples with wiring diagrams that show the basic operation of the sensor. We will look at the different outputs of the sensor and how you can trigger the sensor with a push button. These examples are particularly useful for those looking for Arduino tutorial guidance on ...
