The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

This time, we will build an Obstacle avoiding robot using an ultrasonic sensor and Arduino. Here, an Ultrasonic sensor is used to sense the obstacles in the path by calculating the distance between ...

Also, check all the Arduino-based Robotics projects by following the link. The working of a human following robot using Arduino code and three ultrasonic sensors is an interesting project. What makes ...

These ultrasonic waves travel through air and on colliding with an obstacle, get reflected back. Programming is done in such a manner, that when this obstacle is in the range of 1.4 m of the sensor, ...

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.

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).
