Datasheet

Create the DC motor object

Request the DC motor from the Adafruit_MotorShield:

with getMotor(port#). Port# is which port it is connected to. If you're using M1 its 1, M2 use 2, M3 use 3 and M4 use 4

Connect to the Controller

In your setup() function, call begin() on the Adafruit_MotorShield object:

Set default speed

Set the speed of the motor using setSpeed(

speed

) where the

speed

ranges from 0 (stopped) to 255 (full speed). You

can set the speed whenever you want.

Run the motor

To run the motor, call run(

direction

) where

direction

is FORWARD, BACKWARD or RELEASE. Of course, the Arduino

doesn't actually know if the motor is 'forward' or 'backward', so if you want to change which way it thinks is forward,

simply swap the two wires from the motor to the shield.

Adafruit_DCMotor *myMotor = AFMS.getMotor(1);

AFMS.begin();

myMotor->setSpeed(150);

myMotor->run(FORWARD);
