The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

Arduino uses a tool known as avrdude to convert the C/C++ code written by the end user to hexadecimal code. This hexadecimal code is fed to the microcontroller board for the final execution. A few ...

A USB 2.0 port can provide current up to 500mA and it is more than enough for an Arduino UNO. Depending on the Arduino board, the type of USB connector may vary. For example, Arduino UNO have a USB ...

The board that started Arduino's Nano family, the Nano is a classic platform ideal for basic circuit building and breadboard prototyping. It's similar to the iconic Uno in a lot of ways.
