Percobaan 2 Kondisi 4
SPI-DIPSwitch dan Seven Segment
1. Prosedur [Kembali]
- Rangkailah semua komponen
- Buat program di aplikasi arduino IDE
- Setelah selesai, masukkan program ke arduino
- Jalankan program pada simulasi dan lakukan sesuai kondisi
- Rangkaian
- Prinsip Kerja
Rangkaian diatas adalah salah satu contoh dari komunikasi antara arduino 1 atau arduino master dan arduino 2 yang mmerupakan arduino slave.
Untuk percobaan kalli ini yaitu arduino 1(master) akan menerima input dari dipswitch 1, lalu input akan di proses oleh arduino master, Lalu komunikasi antar arduino master dan slave akan terjadi, arduino mengirimkan data pada arduino 2 atau slave yang akan memproses data dariarduino master lalu akan di tampilkan oleh seven segment.

Jika 3 Switch aktif maka counting 1 - 9 pada digit 1 lalu pada digit 2, Jika 4 Switch aktif maka counting 1 - 9 pada digit 2 lalu pada digit 1
