Distance Sensor Project Build In this video lesson we create a portable distance measuring prototype, using an Arduino Uno R4 WiFi. This project incorporates a HC-SR04 Ultrasonic Sensor, a ‘Go’ button, and the SSD1306 OLED Display. The project is powered by the Sunfounder Breadboard power ban...
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。
Use ultrasonic sensor to do one of the following projects: Collision avoidance for RC car. Detecting the fullness of dustbin. Monitoring level of the dustbin. Automatically open/close the dustbin. Hint: Refer to Arduino - Servo Motor.Additional...

Learn how to use the Arduino ultrasonic sensor to measure distances accurately and enhance your projects with precise distance sensing capabilities.
Arduino - 超声波传感器( Ultrasonic Sensor) HC-SR04超声波传感器使用SONAR来确定物体的距离,就像蝙蝠一样。 它提供出色的非接触式范围检测,具有高精度和稳定的读数,易于使用的包装,从2厘米到400厘米或1英寸到13英尺。 操作不受阳光或黑色材料的影响,虽然声学上很难检测到布料之类的柔软材料。 它配有超声波发射器...
This post is all about the Ultrasonic Sensor HC - SR04. I'll explain how it works, show some features and share an Arduino Project example to help you with your projects. We provide a schematic diagram on how to wire the ultrasonic sensor, and an example
Now the objective of this project is to measure distance using the ultrasonic sensor, and then display that value on the LCD display. You should have the skills you need from the earlier lessons. Try and do this project on your own, but if you get stuck, you can look at my code belo...
So, we have covered pretty much everything that we need to know about using the HC-SR04 Ultrasonic sensor with Arduino. It’s a great sensor for many DIY electronics projects where we need a non-contact distance measuring, detection of presence or objects, level or position something etc. ...
