Original Circuit Diagram: Arduino UNO R3. Now, have a look at our favorite Arduino UNO to find out the AVR chip inside. It is ATMega328P-PU, a low-power version of the traditional ATMega328-PU. The P ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

However, the only Arduino platform included is an Uno R3. You can still create different circuits with this board, though, especially if you're primarily working on beginner projects.

A DIYer has pieced together a railgun of 3D printed pieces and other parts. The 3D printed prototype made by the U.S Navy is considered legit.

Even with more and more devices making the leap to USB-C, the Arduino Uno still proudly sports a comparatively ancient Type-B port. It wouldn’t be a stretch to say that many Hackaday readers … ...

Arduino will continue to make available the Arduino UNO R3 and provide support to all those Arduino enthusiasts that have and would like to create projects using its 8-bit AVR microcontroller.
