The Arduino board exposes most of the microcontroller's I/O pins for use by other circuits. The Diecimila, [a] Duemilanove, [b] and current Uno [c] provide 14 digital I/O pins, six of which can produce pulse-width modulated signals, and six analog inputs, which can also be used as six digital I/O pins. These pins are on the top of the board ...
Arduino Mega compatible board with 16 extra I/O pins and the same a board size as the Arduino Uno. As with the Arduino Mega, most shields that were designed for the Duemilanove, Diecimila, or Uno will fit, but a few shields will not fit because of interference with the extra pins.

GPIO interfaces vary widely. In some cases, they are simple—a group of pins that can switch as a group to either input or output. In others, each pin can be set up to accept or source different logic voltages, with configurable drive strengths and pull ups/downs. Input and output voltages are usually, but not always, limited to the supply ...
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.

Sets the output value on pins configured as outputs. Enables or disables the pull-up resistor on pins configured as inputs. PINx: Input register, used to read an input signal. On some devices, this register can be used for pin toggling: writing a logic one to a PINx bit toggles the corresponding bit in PORTx, irrespective of the setting of the ...
