Project 2.1.4 Combinational Logic Student Design: Date of Birth
Introduction: In your digital electronics class of 20, there is a 6.8% probability that two of you share the same date of birth. This is assuming that you are all the same year level (sophomore/junior). If you are not, the probability would be even lower. Your date of birth may make you unique in your class, but in 2006 there were 263,898,574,096 births world-wide. This means that on a daily basis, over 700,000,000 individuals share the same date of birth
Project Overview- The goal of this project was to design a combinational logic circuit that would be capable of displaying your date of birth on a common cathode seven-segment display. For example, if your birthday was April 16th, 1997, the display should read 041697.
Equipment- In order to assist us in completing this project, we used the CDS (Circuit Design Software) Multisim 12.-0, breadboards, #22 gauge solid wires, the common cathode seven-segment display, and a variety of integrated circuits, depending on the needs of each individual's circuit.

Documentation-
Using the logic expressions I derived from the truth table and Karnaugh Maps I had created, I was able to create a circuit on MultiSim which would display the number 010198 (my birth date) on the seven-segment display.
Breadboarding- The breadboarding process was relatively easy since my circuit only contained (??) integrated circuits, which was due to the fact that some of the outputs were equal to each other, therefore limiting the amount of materials I was required to use.
Conclusion- While completing this project, I learned that many errors when working with digital electronics are simple mistakes such as placing a wire in the wrong location, placing a component backwards into the breadboard, or even forgetting to turn the power on, and that before freaking out and starting back from point A, you should always double check your wiring and make sure that everything is in the correct place. I also learned that it is imperative to remain keen on the fundamentals of digital electronics, as forgetting one little piece of information could leave you stuck on one part of the project for days. The one thing I would do differently next time would be to continue to tinker with my circuit on the CDS to see if there was any way to make it more efficient, as opposed to going with the first design I created. While it wouldn't have impacted my grade in any way, it would have been excellent practice for the future should a situation in which I would have to arise.
