V. Langkah kerja
   1. Siapkan alat dan bahan
   2. Merangkai di protoboard
   3. Buka aplikasi arduino IDE
   4. Masukan program yang diatas
   5. Lalu cek program sudah benar atau belum dengan "klik" tombol "verfy" pada aplikasi arduino
        IDE

    5. Lalu hubungan rangkaian flip flop kek komputer dengan kabel USB kabel CLONE
    6. Lalu klik "upload" seperti pada gambar

       

   7. Jika sudah akanmuncul tulisan "upload done" pada bagian bawah.
