The Arduino UNO is a card based on the ATmega328 microcontroller. The Arduino UNO card comes with 14 pin digital inputs / outputs (6 of which can be used as PWM signals), 6 analog inputs, one 16MHz quartz, one USB connector, one power jack, one connector for ICSP programming and a card reset button.
The card also provides everything you need to support the operation of the microcontroller. To start using the Arduino UNO you simply need to connect the card to a PC via a USB cable or to power the card via an AC / DC adapter or a simple battery.
