BloomBot IoT
IoT robotic flower with servos, sensors, LCD, and remote control.
This project came from wanting something expressive and physical, not just another board demo. I integrated Blynk controls, servo choreography, sensor feedback, and display output into one system.

Project notes
Architecture
How the system works
- Blynk app events map to virtual pin handlers on the Arduino.
- Firmware coordinates servo motion loops with sensor checks.
- LCD and Morse LED signaling provide user feedback state.
Challenges
What made it hard
- Power rails had to be stabilized to avoid brownouts during concurrent servo loads.
- WiFi reliability under demo conditions needed repeated retry logic.
- Timing collisions appeared when actuators and sensing ran simultaneously.
Lessons
What I learned
- Hardware reliability is mostly integration discipline.
- Live demo confidence comes from failure-mode rehearsals.
- A simple feedback channel (LCD/LED) makes debugging way easier.

- Future iterations: improved enclosure, cleaner wiring harness, smoother interpolation.
- I also want to map sentiment-driven inputs to movement patterns.
