Membuat Alat Pengunci Pintu Otomatis ( Door Lock ) Menggunakan RFID Reader ID-12

              Pada sore hari ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang bisa digunakan untuk mengunci pintu secara otomatis dengan kunci berupa kartu atau sejenisnya, jadi alat ini adalah alat inovasi pengganti kunci konvensional yang biasanya diputar atau digeser. Alat ini memiliki 3 unsur penyusun utama, yaitu RFID reader, tag card dan kontroller, RFID reader yang dipakai adalah ID-12, kemudian tag card nya menggunakan tag card bernentuk kartu dan kontrollernya adalah ATMega16. Pengunci pintu menggunakan solenoid door lock dengan tegangan aktif 12 volt dc. Untuk lebih jelasnya berikut adalah skema dan programnya.

a. Minimum System

b. Solenoid Door Lock + Driver 12 volt

c. RFID Reader ID-12

d. Tag card

e. Program Bascom AVR
