WEEK 12 FYP2

 

TROUBLESHOOT PROBLEM

In this week, when i want to test again the project prototype, the motor does not moving. I run troubleshoot for all components but all the components is functional well. I decide to change the battery and the motor start moving but slowly.

    I make decision to do more research about the components and focus more at the motor driver. What i get from the research is, the motor driver need more than 10V supply to run 2 DC motor. I try to use two pieces of 9V battery at my prototype and the motor started to move faster. This week i manage to troubleshoot the problem why my motor driver did not run at high speed, it is because the motor driver did not get enough supply.

WEEK 11 FYP2

 

Troubleshoot for ultrasonic sensor

    In this week, I am deciding to make improvement for my prototype. For ultrasonic sensor i am deciding to make it sense obstacle at 18cm far. This value is a good value because when the sensor detect the obstacle in front of it, the controller can send data to motor driver to decide where to move next. so, the 18cm is a good distance to stop and avoid any collision of the prototype and the obstacle in front of it. 

    if the sensor detect more than 18cm than it is means the obstacle is far with the prototype.

SUBMIT DRAFT

    In week 10, I am submitting my draft report for Chapter 5 to my supervisor for him to check my progress. In this chapter the discussion of the finding will be discussed in this  chapter. As we know, cleaning the whiteboard sometimes can take a lot of teaching time. In addition, cleaning the whiteboard manually will also require a lot of human energy more over if the size of the whiteboard are bigger it also take both of the time and the human energy at the same time.

    In this chapter I need to provide few recommendation for my project and do comclusion from what i get by doing this project.

WEEK 9 FYP2

SET THRESHOLD

during this week, i am doing my research how to set threshold for black marker pen colour. In order to make the colour sensor work for the automatic whiteboard cleaner, the threshold for each colour must be set. To set the threshold, each colour must be tested by using TCS3200.  

    To complete this automatic whiteboard cleaner project, the sensor are going to detect the black colour since the black marker pen are commonly used by the teachers. To detect the black colour, the sensor need to recognize the black colour first by place the sensor at black surface. The sensor are place for a few second on the black surface to determine the threshold.
