Explore the circuit
Tinkercad was used to explore the prototype before the documented hardware build. The case separates that planning activity from the original photograph of the assembled circuit.

THE OBJECTIVE
Smart Home Automation & Security Prototype
A small automation system must translate changes in the physical environment into understandable feedback. The project built that connection incrementally through sensors, indicators, and code.
The smart-home project is a tabletop Arduino prototype. It brings together circuit planning, breadboard assembly, programming, and observation of physical inputs. The word security describes the educational project theme; it is not a claim that the build is a certified home-security product.
THE WORK
My contribution.
- Used Tinkercad to explore a circuit prototype before documenting the hardware build.
- Assembled a breadboard circuit and programmed the system through the Arduino IDE.
- Added door-state and ultrasonic-distance sensing with LED feedback and serial-monitor output.
- Added light-responsive behavior and documented observations in a distance-data chart.

IMPLEMENTATION DETAIL
Inside the coursework.
Connect sensors to responses
Door-state, ultrasonic-distance, and light inputs are connected to LED feedback, serial output, and light-responsive behavior in the documented stages. The learning task is to explain the path from an input to an observable response.
Build incrementally
The presentation combines hardware photographs, circuit views, Arduino code screenshots, and a distance-data chart. These different artifacts help relate the wiring, program logic, and observed output without treating a photograph as a complete functional test.

PROJECT EVIDENCE
What the work produced.
A completed prototype presentation with original hardware photographs, circuit views, Arduino code screenshots, and sensor-output evidence.
Evidence reviewed: CEIS101 final project presentation. Source pages 4–5, 8–10, 12–26.
Original hardware photograph
The retained image shows the actual Arduino and breadboard build from the presentation.
Circuit and code views
The source presentation records the circuit exploration and Arduino implementation.
Sensor-output evidence
Serial-monitor material and a distance-data chart document the original observations.
WHAT I LEARNED
The reasoning behind the result.
Incremental builds make hardware debugging easier: check the wiring, confirm the input in the serial monitor, and then add the response logic.
Hardware work requires checking both a physical connection and the program’s interpretation of it. This project makes that relationship visible through staged builds and several forms of evidence, rather than relying on a finished-looking device photo alone.
WHAT THIS DEMONSTRATES
Practical skills in context.
Connecting hardware inputs, program logic, and observable behavior.
Project deliverable: An incremental sensor-and-indicator prototype, documented with hardware photos and code.
REVIEW BOUNDARIES
What a fresh review would check.
- Confirm pin assignments and wiring against the program before a new run.
- Check sensor readings before adding automated responses.
- Evaluate reliability and safety separately before considering any real home deployment.
Status & scope
Completed tabletop prototype for educational use. Original hardware photographs document the coursework; product certification and home deployment are outside its scope.
Based on the original project presentation, reviewed October 17, 2026. Historical project evidence; not a new execution test.
