The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

The circuit is based around this Sputnik-looking standalone IR temperature sensor which ... sensor with an Arduino Nano and five LEDs that show how hot a beverage is on a scale from 1 to 5.

In the realm of DIY electronics, the Arduino UNO has emerged as a versatile platform for a myriad of projects. One such innovative project is the creation of a low-cost thermal camera, as ...

Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ... from a power wheelchair. An Arduino Mega Pro Mini handles the logic ...
