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. Hooking up to a motor means you can have it spin in both directions; and with PWM
input, you can use your Arduino to make them spin at any speed. Because the L298 has 2 H-bridges, you
can make a robot turn around by spinning each wheel in different directions, and of course go forwards and
backwards.
Now, let's use the I2C Motor Driver to control two DC motors or a stepper rotating clockwise and
anticlockwise.
6.1
Set the address of the I2C Motor Driver

Set the address by dial switch is a new function added to the new I2C Motor Driver.

Then keep the address setup in the program the same as the address setup on the I2C motor
driver. The default address setup in the program is 0x0f.
#define I2CMotorDriverAdd 0x0f // Set the address of the I2CMotorDriver
