I.10. Kalender Digital dengan Tampilan LCD

Sistem Kerja Alat

Arduino membaca data RTC (Real Time Clock) data yang diperoleh berupa jam, menit, detik, hari ke-, tanggal, bulan dan tahun. Hasil pembacaan data RTC kemudian ditampilkan pada LCD 2x16. LCD menampilkan jam , hari dan tanggal. Disamping menapilkan display tersebut jam dapat diseting dengan 4 tombol yaitu tombol Next, Back, Up dan Down.

Kebutuhan Hardware 

• Modul LCD 2x16
• Modul RTC DS1307
• 4 Tombol push ON
• Modul Arduino UNO
• Power supply +9Volt

Jalannya Alat :

1. Koneksikan antara sistem Arduino dengan peripheral lain seperti pada rangkaian (skematik).
2. Pasang power supply (adaptor 9 V) dan hidupkan (colokkan ke sumber PLN 220V) sehingga lampu LED indikator nyala, LCD juga nyala.
3. Tampilan pertama pada LCD :

       4. Setelah 2 detik tampil menjadi tampilan normal yaitu menampilkan jam, hari dan tanggal:

       5. Selanjutnya jika ingin merubah/seting jam/tanggal, tekan tombol Next (tombol 1) sehingga
           tampil Seting RTC selama 2 detik:

        6. Kemudian menampilkan kursor berkedip pada jam:

       7. Tekan tombol UP (Tombol 3) untuk menambah jam, sedangkan untuk mengurangi tekan 

           tombol Down (Tombol 4)

       8. Jika sudah sesuai tekan tombol Next, selanjutnya seting menit prosesnya sama dengan seting 

           jam.
       9. Jika sudah seting menit tekan tombol Next lagi untuk seting detik, dan seterusnya.
      10. Apabila ada setingan yang salah Anda bisa mengulangi dengan menekan tombol Back 

           (Tombol 2).

     11. Setelah semua di seting tekan tombol Next untuk menyimpan data tersebut, sehingga LCd 

           menampilkan “Seting RTC OK!”:

     12. Tampilan LCD kembali ke tampilan Normal.
     13. OK!
