Now is the time to see the sample code (Arduino Uno/Nano Sketch)… To summarize, infrared close proximity sensors are an effective alternative to some other electronic sensors and mechanical switches ...

[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 Arduino Nano Connector Carrier is a compact add-on board designed for the Arduino Nano boards to allow easy connection to ...
