In the present day, technology is drastically enhanced approximately after every
eight months, new innovation establishes and electrical circuit gets more complex
time to time. The project "Circuit that Controls the Ceiling Light and Buzzer in the
Automobile" is a first step to study the similarity between operations of logical
connectives and operations of switching devices. In this project, a powerful
technique, named, Boolean algebra is introduced to simplify complex circuit.
Complex circuit can then be easily simplified and designed by this approach. The
project is mainly based on Boolean algebra and digital circuit design. The ceiling
light control circuit and buzzer control circuit are then created after the
simplification is done by Boolean algebra technique and then implemented it on
programmable logic devices. The success of this project is highly dependent on
what methods are used. Preliminary design, testing and implementation will be the
key for project smoothness. Lastly, this project proves that there is a simpler way to
design a very complicated circuit and how mathematic is related to circuit design
