penjelasan:
Mulanya ada variabel pin berisikan angka 2-9 fungsinya untuk mendeklarasikan pin yg akan digunakan, yaitu pin 2-9
Lalu ada fungsi setup dimana kode dalam fungsi ini dibaca sekali.
Di dalam fungsi setup ada pinMode yang menyatakan pin yang dihubungkan ke pin 2-9 fungsinya sebagai output
lalu ada fungsi loop dimana kode dalam fungsi ini dilakukan perulangan
di Dalam fungsi loop ada pemanggilan fungsi one(), two(), ... , sampai nine() agar 7 segment menampilkan angka 1-9 secara berulang.
Lalu ada fungsi one() yang berisikan
pin 2 memberikan logika LOW atau mati
pin 3, LOW);
pin 4, LOW);
pin 5, LOW);
pin 6, LOW);
pin 7, HIGH);
pin 8, HIGH);
pin 9, LOW);
lalu di delay selama 500ms atau 0,5 detik untuk menampilkan angka 1 di seven segment.
Kemudian ada fungsi two() yang berisikan
pin 2 memberikan logika LOW atau mati
pin 3, HIGH);
pin 4, LOW);
pin 5, HIGH);
pin 6, HIGH);
pin 7, LOW);
pin 8, HIGH);
pin 9, HIGH);
lalu di delay selama 500ms atau 0,5 detik untuk menampilkan angka 2 di seven segment.
begitu seterusnya higga fungsi nine()
pin 2, LOW);
pin 3, HIGH);
pin 4, HIGH);
pin 5, LOW);
pin 6, HIGH);
pin 7, HIGH);
pin 8, HIGH);
pin 9, HIGH);
lalu di delay selama 500ms atau 0,5 detik untuk menampilkan angka 9 di seven segment.
Hingga mencapai 9, maka akan menampilkan angka 1, 2, 3,... 9 dan begitu seterusnya.
