Wiring Printed circuit Board
Objective of This Project
The main objective of the Printed Wiring PCB Board project is to design, construct, and demonstrate a printed wiring board that implements a digital logic circuit for my Circuits Laboratory class. When 5V and CLK cycle is applied to the PCB board, LAM_3353 (my school ID) will display on the 7-segment display one letter/number at a time in the corresponding order.
Utilizing logic gates design on ni multisim & Eagle
To test that my logic is working properly and is displaying LAM_3353 on the 7-segment display in the correct order, I've initially tested it on NI Multisim first. Knowing that my logic is working properly, I then move all the components to Eagle. By doing so, I will be able to design my PCB board for further fabrication process with OSH Park (the company that makes PCB boards).
Finalizing pcb Board for fabrication on Eagle
After putting all the essential parts on Eagle, I can now start designing my board within the software. The most challenging part of this design stage is making sure that there are no "wire crosses" as it can cause some problems with our circuit (short circuit), and fitting all the components on a 2" x 3" board dimension. After receiving my board from OSH Park, I can then solder every logic gates and other components onto the board (as shown in the video below), and it's ready to be tested.

Final Demo
This is the final demo of my project. The 7-segment display is displaying LAM_3353 in the corresponding order every 1 second or so, which is what I wanted. Therefore, it is apparent that the logic are working according to plan.
