Set logical value of digital output pin
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.
If you run a simulation of a model that contains this block without the target hardware, this block does nothing. See Block Produces Zeros or Does Nothing in Simulation.
Enter the number of the digital pin.
Do not assign the same pin number to multiple blocks within the model.
If you set the Target hardware parameter to:
Arduino Mega 2560, enter a pin number from 0 to 53.
Arduino Uno, enter a pin number from 0 to 13.
Arduino Nano, enter a pin number from 0 to 13.
