Page 5: Introduction
1. Introduction The Grove - I2C Motor Driver V1.3 (latest version) can directly control Stepper Motor or DC Motor. Its heart is a dual channel H-bridge driver chip（L298N）that can handle current up to 2A per channel, controlled by an Atmel ATmega8L which handles the I2C communication with for example an Arduino. Both motors can be driven simultaneously while set to a different speed and direction. -

Page 8: Interface Functions
4. Interface functions 78M05 IC: 5v voltage regulator L298 IC: dual full bridge driver Atmega8 IC: Control Motor Rotate. NOTE: Input voltage on screw terminals is regulated to 5v and connected to I2C +5v via a jumper (J4). Remove jumper if both external power via the screw terminals and power via the I2C header are used. Use jumper if 5v should be supplied to the I2C bus. -

Page 10: Usage
6. Usage The I2C Motor Driver can control motor which is based on the chip L298. The L298 is not just a dual motor driver, it is a dual H-bridge. An h-bridge is basically a specific setup of transistors that allow you to switch direction of current. -

How to drive 2 DC motors Note: The first thing to notice however, is that you need an external power source for your DC motors. The 5v pin on the Arduino cannot provide enough power to drive 2 motors, you may damage your Arduino if you do And then program your Arduino as below: #include <Wire.h>... -

delay(1000); MotorDirectionSet(0b0101); //0b0101 Rotating in the opposite direction delay(500); In this program, Arduino first set the speed of the 2 DC motors with the MotorSpeedSetAB()command, and then set the DC motors work directions with MotorDirectionSet() command. Please refer to Function Reference for details, you can download all the demo code in the Resource. - Page 13 MotorDirectionSet(0b1100); delay(4); MotorDirectionSet(0b1000); delay(4); MotorDirectionSet(0b1001); delay(4); This connected 4-wire stepper will rotate; you can adjust the rotation speed or step number in your Arduino program. You can also use some other stepper libraries to control it. For all the demo code please refer to Resource.

7. Function Reference 1. void SteperStepset(unsigned char stepnu) Description: Set the steps you want. stepnu: the Parameter can be 1~255. if 255, the stepper will rotate continuously; Usage: Serial.println("sent command to + direction,100 steps, fast"); SteperStepset(100); 2. void StepperMotorEnable(unsigned char Direction, unsigned char motorspeed) Description: Enable the IIC motor driver to drive a 4-wire stepper. - Page 17 Frequence: the prescale frequency of PWM 6. void MotorDirectionSet(unsigned char Direction) Description: Adjust the direction of the motors Direction:can be Forward/Reverse rotating. Usage: MotorDirectionSet(0b1010); //"0b1010" defines the output polarity, "10" means the //M+ is "positive" while the M- is "negative" // make sure M+ and M- is different polarity when driving DC motors.
