Here is the simple Arduino and 3 Ultrasonic sensor based Human-following robot code that you can use for your project. The MAX_DISTANCE and MIN_DISTANCE_BACK variables set the thresholds for obstacle ...

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, ...

We have previously built many ultrasonic sensors projects, in which the HCSR04 is primarily used ... this ultrasonic transducer’s working frequency is 40 kHz. So, the purpose of using Arduino and this ...

Radar using ultrasonic sensor works in software makes the reaction ... signal to the Arduino if anything comes in the path. then Arduino notifies the software for the affected region. the project ...

You only need to use the famous speed formula: The value of speed is known to us as the sound travels at 343 meters per second. Time will be returned to us by the Arduino Ultrasonic Sensor via the ...

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 ...

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 this ...
