Joshua Brown presented on his CEIS 114 final course project simulating a traffic control system of varying complexity from planning through development stages. The project involved setting up hardware, programming, and networking for an IoT system. Brown created circuits using an ESP32 board, LEDs, resistors, and other components to control lights and detect motion or touches for traffic and pedestrian scenarios. He documented the project flow, circuits, code, and gained skills in circuitry, problem solving, and understanding IoT applications while overcoming difficulties with a non-working buzzer. The course provided a deeper understanding of electrical components and interesting projects that can be built with Arduino.

2. The purpose of this course project
was to simulate a traffic control
system in varying degrees of
complexity from the planning
stage through each
developmental stage.
This course project included
several aspects of IoT including
hardware setup, programming,
and networking.

17. SKILLS GAINED
Further developed my understanding of circuitry.
Honed problem solving and logical analysis skills.
Gained further understanding of the potential exponential
benefits of the implementation of IoT infrastructure.

18. PROJECT DIFFICULTIES
During the final part of the course project my buzzer
stopped working. I tried changing the wires, changing the
output pin, and changing position on the breadboard but
could not revive it.

19. CONCLUSION
I find that this course has provided a deeper
understanding of various electrical components such as
resistors, transistors, capacitors, and much more. I now
have a deeper grasp on how various components work
together to make the devices that we rely on every day.
Not only that, but this course has helped to open my
eyes to the many interesting projects that I can build with
my various Arduino components.
