readPosition

Read position from servo motor connected to Adafruit Motor Shield

Syntax

position = readPosition(s)

Description

position = readPosition(s) reads the position of the motor shaft and returns the value of the position in ratio to the maximum angle of the specified servo motor.

Examples

Read Servo Motor Position

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

Input Arguments

s — Servo motor

servo motor object

Servo motor connection, specified as a servo motor object.

Output Arguments

position — Position of servo motor

numeric

Position of the servo motor, specified as a number representing the angle from 0 to 1.
