Block Diagram . The working of this Arduino smart dustbin is very simple. The ultrasonic sensor acts as the input and the servo motor acts as the output, the Arduino UNO microcontroller is the main ...

How the Arduino ultrasonic sensor actually works. To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...

Ultrasonic Sensor Measurement: The HC-SR04 ultrasonic sensor measures the distance to an object by emitting a sound wave and measuring the time it takes for the echo to return. The sensor is connected ...
