WEEK 4

                                                                

 In this week 4, i am consulting with my supervisor to make my automatic whiteboard cleaner using ultrasonic sensor and colour sensor.

    The ultrasonic sensor are used to detect any obstacle at the whiteboard. Since the automatic whiteboard cleaner are moving automatically and freely on the whiteboard that are attached at the wall, an obstacle will be put together at the border of the whiteboard. The purpose of this barrier at the border of the whiteboard is to make sure the ultrasonic sensor can sense it and send the data to the controller to turn to another way.

    The color sensor are use to to detect the residue of ink at the whiteboard. when it detect the residue the data will be send to the controller, and from the data it will send to the motor driver.
