I started learning robotics when, I bought my first Arduino kit of EPICTAC company, I never used to lose my confidence and I kept on doing it till a got success or till my project worked, I thought to share my Innovations to help other's to learn something............................ by my project's contributions.

EXPANDED TECHNICAL DETAILS

Multi-Sensory Feedback

This project focuses on the synchronization of light and sound to create an engaging user experience or a logic game.

  • Visual Arrays: Uses multiple LEDs in complex patterns (Circular, Sine Wave, or Sequential).
  • Acoustic Harmonics: A Piezo Buzzer is used not just for beeps, but for playing specific musical notes or "satisfying" frequencies that correspond to the LED transitions.

Firmware Algorithms

The Arduino handles simultaneous timing tasks using millis() instead of delay(), allowing the LED patterns to remain smooth while the buzzer plays complex frequencies. This is a great example of non-blocking code implementation in embedded systems.
