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, ...

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 ...

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 ...

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 ...

This Robot will use an ultrasonic sensor and will ... used in this project is given below. Now as we have a complete list of all the components, let us move a step ahead and study the working of each ...

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 ...

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 ...

I will use this sensor (or its latest version) in a more complex project in the next part of this post. Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the ...
