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 ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used ... The presentation material and the code can be ...

[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.

Likely applications are button designs and proximity ... and as an Arduino-compatible shield. It can be used to add a capacitive-button user interface to Arduino projects. To apply for the MBR3 kit, ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

In the microcontroller era today, Arduino is more than just a tool to accomplish ... near 0.3s to 18s by the onboard potentiometer. Another sensor suitable for our project is the Infrared Proximity ...
