Ultrasonic sensors are commonly used in Arduino projects for distance measurement. An ultrasonic sensor is a device that uses ultrasonic waves for distance measurement. It works on the principle of ...

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, ...

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 ...

In this project, we will build such an obstacle-avoiding robot to learn the basics of how they work and how to improve them. Even though there are multiple methods to detect obstacles, we would be ...

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 ...

Arduino Code for Speed Sensor In general, the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When ...

Abstract In this study, a simple Arduino-based experiment was designed to examine the acceleration of the object during free fall and to calculate the value of “g” (acceleration due to gravity).
