Piezoelectric Sensors: Detect impact and vibrations on racket face Vibration Threshold Calibration: Differentiates sweet spot vs. off-center hits Instant Feedback: Displays result through a serial monitor (future scope: LEDs/app) Gamified Scoring: Rewards precision and encourages self-improvement Lightweight & Compact Design: Doesn’t affect racket balance Open-source Hardware & Code: Enables further customization and scaling 

Idea: VIBE-SPOT is a sensor-based tennis racket attachment that detects whether the player has hit the sweet spot using piezoelectric sensors to measure vibration patterns. It identifies off-center hits and provides immediate feedback via a serial monitor, with future integration planned for LEDs or mobile notifications. A gamified scoring system also helps track and motivate player progress. Objectives: 🎯 Detect sweet spot hits using piezo sensors in real time ⚡ Provide instant feedback on shot quality without relying on external coaching 🛡️ Reduce injury risks by detecting and minimizing excessive vibrations 🕹️ Gamify the training process to make practice more engaging 💡 Develop a lightweight, plug-and-play module easily attachable to any racket 📊 Promote data-driven training for precision, confidence, and consistency
