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 ...

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 ...

Arduino Code for Human Following Robot . Here is the simple Arduino and 3 Ultrasonic sensor based Human-following robot code that you can use for your project. This code reads the distances from three ...

Ultrasonic Sensor Measurement: The HC-SR04 ultrasonic sensor measures the distance to an object by emitting a sound wave and measuring the time it takes for the echo to return. The sensor is connected ...

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, ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...
