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

/Firmware - Arduino example code. Make sure to check the pin definitions and what you are connecting to. Documentation Hookup Guide - Basic hookup and project example using the ultrasonic sensor. (Note: The example code used in this tutorial is slightly different than the basic example used ...
A sensor is a device that converts one type of energy to another. Arduino is a small microcontroller board with a USB plug to connect to the computer. The Arduino board senses the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lcds, ...
The HC-SR04 is a commonly available low cost ultrasonic range sensor. It is dumber than some, which is why it is cheaper. Your Arduino has to handle the timing and calculations. I'm selling these in packs of 4. Also optionally add 200mm/8" cables. ...
