WEEK 14

To Preparation and Present about the project

The presentation will start on 8/11/12 (Thursday) week 14 and all FYP Degree sem 2 will present their project. Each student will be examined by two checks,.  My Assessors are also many suggestions for my project and insyakallah I will propose my ideas on Assessors to my supervisor Mr. Ahmad Bin Che Suhairi Rizuan.

WEEK 13

Poster

WEEK 11 & WEEK 12

Circuit Problem 

problematic circuit, the output is not available and I will find the problem and troubleshooting be done......
