delay(2000);

}

Program Function: the first group rotate in C.W.(Clockwise) for 2s and rotate in anti-clockwise for 2s,

then stop for 2s and followed by recycling.

Functions:

1. Create a motor object

2. DFRobot_Motor motor1(M1)

M1 represents the first group DC motor M1A(+),M1B(-

)

3. Initiate the motor drive, read Product ID and Version ID, and print to the serial port.

4.

init()

5. Set speed

6.

speed(val)

0<=val<=4096(the maximum speed is 4096)

7. Set direction and start to rotate

8. start(dir)

dir=CW: rotate in C.W.(Clockwise) dir=CCW: rotate in anti-clockwi

Stepper Motor Drive

FireBeetle Covers-DC Motor&Stepper Driver can control two-channel two-phase four-wire stepper

motors simultaneously. It adopts DC motor interface and control via IIC interface. The test explains

the way demonstrates how to control a two-channel two-phase four-wire stepper motor by Arduino

main board.
