The I2C (read as I square C) smart DC motor controller is designed using the Atmel 8-bit AVR Atmega168 microcontroller and configured to act as the I2C slave device where it could be controlled by other microcontroller or microprocessor through the I2C SDA (serial data) and SCL (serial clock) interface. In the first part we have accomplished a basic DC motor controller tasks i.e. differential steering and speed control using pulse width modulation (PWM). In this second part article I will put all the features described in Building the I2C Smart DC Motor Controller with Atmel AVR Microcontroller article – Part 1, this mean we will adding more features to the I2C smart DC motor controller firmware which include wheel rotation and servo control.
