[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 ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The already-large family of Arduino boards is enriched with a new entry, the Arduino Nano RP2040 Connect, integrating the RP2040 microcontroller developed by Raspberry Pi Foundation with the u-blox ...
