[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 ...

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 ...

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 ...

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 ...

Sure, modern paper shredders already have sensors that tell you when the bin is full, but if your machine lacks this feature, you can just build it a custom sensor with an Arduino Uno.

In order to find the dynamic TDC a microwave sensor was installed on the head and a proximity probe on the wall of 4-cyl SI engines. The dynamic TDC determined by the microwave system exhibited fairly ...
