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引脚会进入低电平状态。
Wiring – Connecting MaxBotix MB1240 to Arduino UNO As mentioned in the introduction, MaxBotix sensors can be operated in different modes. The wiring diagrams below show you how you can connect the MB1240 sensor to the Arduino for analog voltage or pulse width operation. You can solder the wir...
In this tutorial, you will learn how the sensor works and how to use it with Arduino.I have included 5 examples with a wiring diagram and code so you can start experimenting with your sensor. We will first look at an example that does not use an Arduino library. Next, I will show ...
