🛠️ Required Components: https://maisonup.in/shop/
🔹 ESP32 Development Board
🔹 DFPlayer Mini MP3 Module
🔹 1.3-inch OLED Display
🔹 Three Push Buttons (Play/Pause, Next, Volume)
🔹 1000uF Capacitor (Power Stability)
🔹 Speaker (3W or 5W Recommended)

🔧 Step-by-Step Guide:
1️⃣ Format your microSD card (FAT32) & name MP3 files numerically
2️⃣ Connect buttons to GPIO 25, 33, and 32
3️⃣ Initialize DFPlayer Mini on GPIO 26 & 27
4️⃣ Set up an OLED screen on GPIO 22 & 21 to display track info
5️⃣ Upload code & start playing music! 🎵

🎚️ Enhancing Audio Output:

The built-in amplifier is great for small projects
For better sound clarity & loudness, connect an external amplifier (PAM8403 or TPA3118)
Power the amp with a 12V adapter for optimal output
🔊 Listen to the Difference:
🔹 Left Channel → Without Amplifier
🔹 Right Channel → With Amplifier

💡 Troubleshooting Tips:
⚠️ DFPlayer not responding? Check wiring & baud rate settings
⚠️ Buttons not working? Verify GPIO connections in code
⚠️ Audio distortion? Lower volume in software or use an amplifier
