A-SAL07 - Tune with Tech: Arduino Melody Maker

🎶 Tune with Tech: Arduino Melody Maker
Components Used: Arduino, 4x4 Keypad, Buzzer, RGB LED, 16x2 LCD (Non-I2C)

---

🔍 Project Overview:
"Tune with Tech: Arduino Melody Maker" is an interactive and educational electronics project designed to introduce students and hobbyists to the exciting world of sound generation and embedded systems using Arduino.
By combining a 4x4 keypad, buzzer, RGB LED, and an LCD display, this project allows users to play musical notes by pressing keys on the keypad. Each key triggers a different tone (like Sa, Re, Ga, Ma…) and simultaneously lights up the RGB LED with a unique color representing that note. The LCD displays the name of the note being played, providing visual feedback and a more immersive learning experience.

🎯 Project Objectives:
To understand tone generation using Arduino and buzzers.
To learn how to interface a 4x4 matrix keypad with Arduino.
To provide visual feedback using an LCD and RGB LED.
To make learning music theory (basic notes) fun and interactive through technology.

🧠 Key Features:
🎼 Play Musical Notes: Each key on the keypad is mapped to a specific musical note (Sa to Sa’).
💡 RGB Feedback: Different colors light up for each note, making it visually engaging.
📟 LCD Display: Shows the name of the note as it’s played.
🔊 Buzzer Output: Produces clear and accurate tones for each musical key.
🎮 Real-time Interaction: Press and play—no delays or complex menus.
