Arduino Smart Dustbin using Ultrasonic Sensor Smart Dustbin as its name represents its work smartly or we can say that it is an automatic dustbin. Smart Dustbin is a very good project from the Arduino. We can say that It is a decent gadget to make your home clean and attractive. kids spr...
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 bank. The arduino is powered by the power bank as well, so the project can operate totally portable. When the device is turned on...
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。
