CEIS114 / COMPLETED ACADEMIC PROJECT
IoT Traffic Light Controller Prototype
Coordinating signals, inputs, and display feedback.
An ESP32 coursework prototype that developed from a basic LED traffic sequence into a multi-signal controller with crosswalk and emergency features.
DeVry University coursework01 / THE OBJECTIVE
IoT Traffic Light Controller Prototype
Adding a pedestrian request or emergency signal changes how a controller must coordinate its outputs. The project explored that coordination in a small hardware demonstration.
02 / THE WORK
My contribution.
- Assembled and programmed a basic ESP32 traffic-light circuit, then extended it to two sets of signals.
- Added a push-button crosswalk input and documented the corresponding code and serial output.
- Extended the hardware with an LCD, buzzer, and emergency indicator.
- Documented Wi-Fi scanning and a later web-control stage; worked through pin-placement, LCD-adjustment, and code issues.

03 / PROJECT EVIDENCE
What the work produced.
A completed presentation documenting staged circuit builds, original hardware photographs, code, serial output, and collaboration evidence.

Evidence reviewed: CEIS114 final project presentation. Source pages 5–25; collaboration and challenges on pages 26–27.
04 / WHAT I LEARNED
The reasoning behind the result.
When a system grows, each new input or output needs to be checked against the behavior already in place. Clear pin mapping and staged tests help isolate faults.
05 / WHAT THIS DEMONSTRATES
Practical skills in context.
Extending control logic while checking interactions between inputs and outputs.
Project deliverable: Staged controller builds with code, serial output, and documented collaboration.
Status & scope
Completed tabletop prototype with documented collaboration. Web-control security was not independently verified. The project demonstrates coursework rather than a system approved for road use.
Based on the original project presentation, reviewed October 17, 2026. Historical project evidence; not a new execution test.
