After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

[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 ...

The usual solution is to use some sort of statistical averaging to reduce noise in sensor readings. This is often called “filtering”. The goal of this quick project is to experiment with two types of ...

Why not create your very own high speed camera trigger using a Arduino, piezoelectric sensor (as a sound sensor), a DSLR camera and an external flash.

These little Arduino boards are a real boon to amateur electronics tinkerers: cheap, versatile, and very small. This guy had the idea to make a high-speed photography setup using one, instead of ...

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 ...
