In this course we learned about logic circuits, logic gates, binary, flip flops counters. Basically this course taught us all the basic ground level technology used for all kinds of modern technology. I even understand the main concept of circuits in this course. Besides the regular lectures there were some projects also done during this course. We created an initial system for modern lift or elevator. This project helped us to understand the modern elevator system. How each level is counted using counter while operating the lift. We also learned the main difference between digital and analogue systems and the technologies. What are the main purpose of using this different technologies in different fields. I sharing some of the proofs of our activities during this course completion. We did labs and many other activities as well to enhance out knowledge.
