DigitalDoorLockSystem
Arduino-powered door lock using a keypad, I2C LCD, and servo motor. Password validation with real-time LCD feedback.
Problem
The project needed a focused implementation that turned a practical requirement into a usable, maintainable software artifact.
Solution
I designed the core flow, selected a stack that matched the project constraints, and implemented the key user-facing and technical features end to end.
Impact
Converted a real requirement into a working product or technical prototype.
Applied the stack in a practical context beyond isolated coursework.
Created a foundation that can be documented, extended, or productized further.
Highlights
End-to-end implementation
Responsive user experience
Practical technical decision-making
Architecture
Arduino Nano
C/C++

Next Steps
Add richer public documentation and screenshots.
Publish deeper implementation notes and measurable outcomes.
