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 ...

It has a distance sensor to calculate the distance to walls and objects, an accelerometer, light-sensing phototransistors to seek out light or dark, edge detection sensors, infrared transmitters ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

ArduSat is an Arduino-powered satellite being funded through kickstarter to foster open satellite access and the collection of data from sensors in space. It will be able to run code for up to a ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...
