Digital Output

Set logical value of digital output pin

Add-On Required: This feature requires the Simulink Support Package for Arduino Hardware add-on.

Library

Simulink Support Package for Arduino^® Hardware/Common

Set the logical value of a digital pin on the Arduino hardware:

Sending 1 to the block input sets the logical value of the digital pin HIGH to 5 V or 3.3 V, depending on the board voltage.
Sending 0 to the block input sets the logical value of the digital pin LOW to 0 V.

The block input inherits the data type of the upstream block, and internally converts it to boolean.

During simulations without the hardware, this block does nothing.

Pin number

Enter the number of the digital pin.

Do not assign the same pin number for different types of blocks as this may cause resource management conflicts.

To know how to assign pins or to know about the fixed pins for the block, see Pin Mapping for Arduino Timer Independent Blocks.
