### Description

The UNO card has a set of logical ports (digital) which are used for writing or reading data from a component.

To map a UNO, ports 2-13 are available (0 and 1 are used for serial transmission). For MEGA board, ports 2-53 are available. The port takes the low logic level (0) or logic high (1) which corresponds to the reference voltage.

Do note that the minimum sampling rate is 8 ms for this block.

### Dialog box

The digital port number is between 2 and 53, chosen based on his Arduino.

The card number can not be changed at this time.

### Example 1

The example below shows the use of the block in the case of an assembly consisting of a switch which is connected to a digital pin 7 and a LED which connected to digital port 10. Pressing the button causes the LED to light up.
