* Programming - The Arduino/Genuino Uno can be programmed with the (Arduino Software (IDE)). * Warnings - The Arduino/Genuino Uno has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. * Differences with other boards - The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. * Power - The Arduino/Genuino Uno board can be powered via the USB connection or with an external power supply. * Memory - The ATmega328 has 32 KB (with 0.5 KB occupied by the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library). * Input and Output - See the mapping between Arduino pins and ATmega328P ports. The mapping for the Atmega8, 168, and 328 is identical. * Communication - Arduino/Genuino Uno has a number of facilities for communicating with a computer, another Arduino/Genuino board, or other microcontrollers. * Automatic (Software) Reset - Rather than requiring a physical press of the reset button before an upload, the Arduino/Genuino Uno board is designed in a way that allows it to be reset by software running on a connected computer.
