writeDigitalPin

Write data to digital pin on Arduino hardware

Syntax

writeDigitalPin(a,pin,value)

Description

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

Examples

Write to Digital Pin

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

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

Input Arguments

a — Arduino hardware connection

object

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

pin — Digital pin number

character vector

Digital pin number on the hardware, specified as a character vector.

value — Value of the digital data

logical

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.

More About

Code Generation Using MATLAB Function Block

• 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.
