A small tutorial for interfacing a ultrasonic sensor with arduino this uses a sensor called HC-SR04 which sends ultrasonic waves to detect objects in front of it.

If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

Abstract: This paper shows non-contact water level monitoring system implemented using LabVIEW and arduino. Water depth of the tank is measured by Ultrasonic sensor. Hence the water level present in ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Abstract: A simple robotics project simulated in Tinkercad based on Arduino Uno. It uses ultrasonic sensors for obstacle detection and can do basic movements using DC motors. The primary objective of ...

Our IoT-Based Smart Bin project features a custom-built IoT system and Firebase database, using the Arduino Uno R4 WiFi. Dual ultrasonic sensors handle motion and fill-level monitoring, with an ...

Previously, we have build many robots using arduino including an Obstacle Avoiding Robot using Arduino Uno and Ultrasonic Sensor, you can also check them out if you are interested. In this ...
