In this project an obstacle detection system will be built with Arduino. This system mainly uses an ultrasound sensor and LED.When the ultrasonic sensor detects an obstacle at a distance < 3cm, ...

Written by AnyalogbuEC for demonstration purposes. This program measures distance using an ultrasonic sensor. Visual indication of distance is provided by an LED. The distance is also displayed on an ...

Ultrasonic Sensor Module. There are many types of Arduino distance sensors, but in this project we have used the HC-SR04 to measure distance in range of 2cm-400cm with an accuracy of 3mm.The sensor ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Ultrasonic Module with Arduino Connection Diagram. The Following connections are made between Arduino UNO and the Sensor: Arduino Code. As discussed in the working section, we need to send 10uS pulses ...

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 ...

This Arduino-based distance meter can be used for measuring the distance between the sensor and object in the range of 2cm to 400cm using an ultrasonic sensor.The author’s prototype and ultrasonic ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...
