Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

The build relies on an Arduino Uno as the brains ... [Maker 101] gave the Arduino an infrared sensor which can pick up signals from a simple IR remote control. It can be driven backwards and ...

Then, chances are you already know what an Arduino is ... such as a smart IR thermometer, RGB goggles, and a universal TV remote. Meanwhile, the Uno is more suitable for general-purpose projects.

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

Then, an Arduino board might be exactly what you're looking for. This open-source hardware platform comes in a multitude of versions, from the classic Uno to ... multi-sensor projects that may ...
