1. Prosedur [Kembali]

1.  Rangkai komponen sesuai percobaan dan kondisi yang dipilih.

2. Buat program menggunakan Arduino IDE.

3. Compile program yang telah dibuat lalu Upload ke dalam Arduino Uno.

4. Saat Proses Penguploadan porgram, lepas pin rx tx pada arduino master dengan arduino slave

5. Uji coba program pada rangkaian percobaan sesuai dengan kondisi yang diinginkan.

6. Selesai

• Rangkaian Simulasi 

• Prinsip Kerja 

Pada rangkaian kita menggunakan 2 arduino yaitu untuk master dan slave yang mana input dari master yaitu dipswitch sedangkan pada slave terhubung ke 7 segment.
