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 ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. ... Looking through the code, looks like serial between Arduino and Pi.

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 ...

An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range. Upon sensing an obstacle, ... the Arduino code is equally basic, too.

Patrick explains a little more about the new Arduino ultrasonic experiment kit and its functionality : This bad boy can be re-programmed with your own code, and the included code samples can be ...

Designed for short-range applications from 2" to 6", the RPS-400-6 ultrasonic sensor measures 0.75" x 2" x 1.5" and comes standard with integrated background suppression.

Runner and Arduino enthusiast Nikodem Bartnik has created a DIY 100m sprint timer which is placed at the finish line and signals the start of timing via an audible bleep from its integrated speaker.
