GuitarPal is an embedded system designed to assist beginners in learning the guitar more effectively and interactively. By placing addressable LEDs under each string at every fret and using touch sensors to detect finger placement, this system provides real-time visual guidance and feedback through a connected mobile app.

To create a low-cost, extendable guitar learning tool that:

• Guides users with LED-lit note/chord positions
• Detects and verifies correct finger placement
• Provides real-time feedback via a mobile application
• Makes practice intuitive and motivating for beginners

• Individually addressable LED strips for visual fret guidance
• Capacitive/resistive touch sensors to detect correct finger positions (detecting method is TBD)
• Bluetooth communication with a custom mobile app
• Real-time accuracy feedback through the app

• Microcontroller: ESP32 (Wi-Fi/Bluetooth, GPIO support)
• Sensors: (TBD)
• Visuals: WS2812B addressable RGB LED strips

Week(s)	Milestone
Week 1–2	🔧 Research & Requirements Finalization • Literature review • Component sourcing (ESP32, LEDs, sensors) • Confirm fretboard layout and hardware design
Week 3–4	💡 Hardware Prototyping • LED control with ESP32 • Basic touch sensor testing • Breadboard layout & power setup
Week 5–6	🔌 Bluetooth Communication • Set up BLE with ESP32 • Mobile app connects to hardware • Test sending commands from app to light LEDs
Week 7–8	📱 Mobile App Core Features • Flutter UI for chord/note selection • Integrate with BLE logic • Touch sensor feedback shown on app
Week 9–10	🧪 Integration & Testing • Full system testing (LED + touch + app) • Debug interaction delays & UI bugs • Fine-tune fretboard response
Week 11–12	✅ Finalization & Polish • Refactor code & optimize power usage • Document system and app • Prepare for presentation/demo • Buffer time for unexpected issues

• Total Estimated Weekly Commitment: ~8–10 hrs (flexible)
