Cara Masuk Cap Jari Ke Fingerprint AS608 dengan ESP 32

✅ FULL CODING — Enroll + Delete + Verify (ESP32 + Fingerprint AS608)

====== MENU FINGERPRINT ======

1. Enroll (Daftar cap jari)

2. Delete (Padam cap jari)

3. Verify (Scan & semak)

================================

// Pada Serial Tekan 1dan tekan id yg nak save cap jari contoh 11(akan intall id 1)
//atau 12(akan intal id 2) sama fungsi jika hendak padam tekan 2(tekan id ) contoh 22 (id 2 padam )

//Start Coding dari bawah ni copy dan letak kat Arduino IDE
