The ATmega328 has only 2KB of RAM, but 32KB of Flash. ... The 16u2 is normally used as the Arduino Uno’s USB interface. The only external hardware needed is a single 120 ohm resistor.

Dans ce dossier, vous trouverez les schémas des cartes Arduino Uno et Nano ainsi que la documentation technique du µC ATMega 328. Le document le plus important reste celui des PINOUT décrivant pour ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

Those of you who’ve been around a while will probably have guessed how this was done, as the ATmega328 in the Uno has no MMU and is in to way powerful enough for the job.

This repository contains a collection of embedded systems projects using Atmega8, Arduino, and Eagle PCB. Each project is designed to help you learn the basics of hardware programming, circuit design, ...

In the Arduino UNO board, the main component is the ATMega328P. ... The ATMega328 and ATmega16U2 have a maximum input voltage of around 5V and most modules or accessories work on either 5V or 3.3V.
