Week 12 - April 28th Last project lab session today .....

Finally the pressure is off as everything come to an end.  I am overwhelmed because I finish everything which I was required to hand up. Meaning I done the complete board with everything working properly and thus, achieving my aims. I spent all the holiday doing the report and some other assignments in other modules, in the lab I completed the whole report then handle up the printed PDF files. The final part was to submit the same PDF report on the moodle; which I did and finally handing up the complete hardware at the very end. Overall, everything went as smooth as I wanted it to be despite the lack of not using the Humidity sensor (which is a Surface Mount Technology) in this project. 

The finished product.
