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

Description

This object represents a connection to a servo motor with the specified motor number on an MKR Motor Carrier or a Nano Motor Carrier. You can control the servo motor using the functions listed under Object Functions.

Creation

Syntax

servoObj = servo(mcObj,motornumber)

Description

servoObj = servo(mcObj,motornumber) creates a connection to the servo motor at the specified motor number on the Arduino® MKR Motor Carrier or Nano Motor Carrier.

example

Input Arguments

Create a connection to the Nano Motor Carrier.

mcObj = motorCarrier(arduinoObj)
mcObj = 
  MotorCarrier with properties:

          SCLPin: 'A5'
          SDAPin: 'A4'
      I2CAddress: 102 ('0x66')

Create a servo motor connection.

servoObj = servo(mcObj,4)
servoObj =
