Abstract
The Deconstructed 555 Timer and Application Circuits for Interactive Educational Experience offers interactional implementation of three fully discrete 555 Timer example circuits. The research project goal was to gain knowledge of the 555 Timer by deconstructing the device down to the component level. Three independent example application circuits, which showcase the application versatility of the 555 Timer in different modes, include Monostable, Astable, and Bistable circuits. Each mode has a hardware interface that can be used to adjust the operation of the 555 Timer allowing for a full interactive experience. The user can observe the differences in the internal working of the 555 Timer for the implemented applications. The built product is an educational and engaging interactive board which uses LEDs and LCD displays to describe the internal functionality of a 555 Timer and its application versatility. The undergraduate research concentrated on building skills in circuit design and product development.
Biography
Preston Carroll started out by earning an Associates Degree in Industrial Maintenance Technology at OTC. After a break from school he realized what trully interested him and set out to earn his Bachelors Degree in Electrical Engineering. Having experienced many odd jobs up to that point, he then obtained an internship at John Deere as a quality engineer. Through his journey back to college he also decided to pursue a minor in Computer Engineering and took up the position as a teaching assistant for the Circuits I Laboratory. His love for learning and helping others has helped fuel him through this long journey which brings us to the present day where he and two fellow students undertook the responsibility of an OURE project to build a discrete 555 Timer that shows the architecture and modes of the infamous IC.
In 2022, Benjamin Cuebas graduated from Ozarks Technical Community College with an Associate's degree in Electrical Engineering. Since then, he has been taking Electrical Engineering courses at the Missouri State University Cooperative Engineering program and expects to graduate with his BS in spring 2025. Benjamin has worked as an electrician and electronics technician during his pursuit of an EE degree. In the summer of 2023, he did his first engineering internship, where he designed test equipment for RF MM/Cs. Currently, Benjamin stays busy with schoolwork, OUREs, Embedded Systems Club, and by participating in the Missouri State University IEEE student chapter.
Justin Fausto began attending Ozarks Technical Community College in the fall of 2020 and graduated in the spring of 2022 with an associate's degree in electrical engineering. In the fall of 2022, he began attending Missouri University of Science & Technology, and will graduate with a bachelor's degree in electrical engineering with a minor in Computer Engineering in the spring of 2025. Currently, he serves as an Undergraduate Teaching Assistant, facilitating the laboratory portion of the course Introduction to Digital Logic. He is also the current president of a student organization on campus, the Embedded Systems Club. Justin is employed in an engineering student co-op program at John Deere Remanufacturing as a Manufacturing Engineering Technician in their electronics division.
