writeDigitalPin

Write data to a specified pin on Arduino hardware

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

Syntax

writeDigitalPin(a,pin,value)

writeDigitalPin(a,pin,value) writes the specified value to the specified pin on the Arduino^® hardware in the connection a.

This example uses:

Write a value to digital pin 5 with an LED to turn it on.

a = arduino();
writeDigitalPin(a,'D5',1);

Arduino hardware connection created using arduino, specified as an object.

Pin number on the hardware, specified as a character vector.

Note

If you are using an analog pin to write a digital value, the pin will be configured in DigitalOutput mode.

Value of digital data to write to the specified pin on hardware, specified as a logical value of 0 and 1 or true and false.

Use writeDigitalPin in a MATLAB^® Function block with the Simulink^® Support Package for Arduino Hardware to generate code that can be deployed on Arduino Hardware.
Configure the Arduino peripherals to the appropriate mode using configurePin before using writeDigitalPin in the MATLAB Function block.
