Get logical value of digital input pin
Get the logical value of a digital pin on the Arduino hardware:
If the logical value of the digital pin is LOW, the block outputs 0.
If the logical value of the digital pin is HIGH, the block outputs 1.
The data type of the block output is uint8.
If you run a simulation of a model that contains this block without the target hardware, this block outputs zeroes. 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.
Specify how often this block reads the pin value, in seconds. Enter a value greater than zero. This value defaults to a sample time of 1 second. The minimum value is 0.000001 second.
Smaller values require the processor to complete the same number of instructions in less time, which can cause task overruns.
