This is an Arduino project using an HC-SR04 Ultrasonic Sensor and LEDs to measure the distance of objects, similar to a scale. When an object comes close to the HC-SR04 ultrasonic sensor, it indicates ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

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: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
