Input and Output Each of the 14 digital pins on the Arduino Uno can be used as an ... SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI library. LED: 13.

D10, D11, D12, and D13 as SPI communication pins, used as SS, MOSI, MISO, and SCK respectively; ... Both the Arduino Nano and Uno can be powered via their integrated USB connectors.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...
