Frequently Asked Questions

What is the difference between Arduino UNO Rev3 and UNO R4?
The UNO Rev3 (ATmega328P) is the classic, battle-tested version — ideal for learning and simple to moderate projects. The UNO R4 features a more powerful processor (Renesas RA4M1) and additional features. For a first board and education, the Rev3 remains the golden choice due to its massive community and documentation.

What can I build with the Arduino UNO Rev3?
Almost anything: temperature & humidity stations, smart irrigation systems, robotic arms, automatic lighting, weather stations, games, 3D printer controllers, and much more. The Arduino UNO Rev3 is the most documented microcontroller board in the world.

Do I need prior programming knowledge?
No. The Arduino IDE is designed for beginners, with simple syntax based on C/C++. There are hundreds of free tutorials in both Greek and English, as well as ready-made Arduino Starter Kits that include all the components you need.
