Debugging and Troubleshooting
Common Issues and Fixes
Problem Cause Solution
LED not lighting Loose connection Check wiring
Wrong color displayed Incorrect mapping Re-check AI script
AI not detecting face Camera issue Adjust lighting & camera position
Final Testing and Presentation
Test the Mood Lamp with various facial expressions.
Present the project and discuss possible improvements (e.g., adding sound effects).
By merging face recognition AI with Arduino-driven LED effects, you’ve built an interactive
Mood Lamp that can visually reflect someone’s emotional state. Whether you use a simple RGB
LED for quick color changes or a NeoPixel strip for a dazzling show, the result is a project that
merges human expression with light-based feedback, illustrating the powerful synergy of AI and
microcontroller technology.
Remember: Facial recognition transforms a simple microcontroller project into a
device that understands and reacts to emotional cues. By combining external AI tools with
Arduino-based lights—whether a basic RGB or a NeoPixel array—you create an engaging,
expressive system that bridges the gap between humans and machines.
