A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...

If you are interested in creating a low-cost contactless infrared thermometer powered by the Arduino platform, you may be interested in a new project published on the Instructables website and ...

This project involves designing and constructing a digital tachometer using an Arduino Nano. The tachometer measures the rotational speed of a motor or any rotating object and displays the RPM ...

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 ...

Abstract: Presence of doctor is essential for proper patient care. But he cannot be present on each and every place to provide medication or treatment. So remote monitoring of a patient is the right ...
