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.

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 ...

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 ...
