This example uses:

Open Live Script

Connect to Arduino hardware, and create an add-on connection to an Adafruit Motor Shield.

a = arduino('COM4','Uno','Libraries','Adafruit/MotorShieldV2');
shield = addon(a,'Adafruit/MotorShieldV2');

Create a servo motor connection to motor number 1 on the shield.

s = servo(shield,1);

Read the position of the servo.

position = readPosition(s)
position = 0.5200
