Each of the 14 digital pins on the 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 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by...

On the Arduino Uno, port D contains pins 0 to 7, port B pins 8 to 13, and port C A0 to A5. There are 3 registers to control the I/O (where x is the port letter): DDRx: Data Direction Register: this sets whether the pins of the port are inputs(1) or outputs (0). (pin...
Arduino Hardware Interrupt PinsOn the Arduino Uno there are only two pins that are hardware interrupt capable:Pin 2 –Interrupt vector 0 Pin 3 –Interrupt vector 1.Not all Arduino boards are limited to 2 Hardware Interrupt pins, some Arduino boards have many more. The following chart shows ...
