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 ...

Among all the Arduino boards, the Uno is most folks' go-to choice ... (found on the board's Arduino Store page). PWM pins in the diagram have the same tilde sign in front of the pin numbers.

Conversely, the Uno's pins are female. 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 ...

On the Uno, Nano, and Mini ... check out its pinout diagram documentation (found on the board's Arduino Store page). PWM pins in the diagram have the same tilde sign in front of the pin numbers.
