Input and Output Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), ... PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the ...

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 ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

The pinout diagrams are simple, but they're easy to read, and especially helpful for beginners. You can print them out full size so you can set your Arduino Uno, ATMega, or ATTiny right on top for ...
