LED seven segment

PROYEK ARDUINO

LED seven segment

Sekarang langsung Saja ke percobaan arduino dengan seven segment,
Bahan – Bahan  yang perlu disiapkan adalah :

• projectboard
• arduino uno
• seven segment (boleh anoda maupun katoda)
• kabel jumper
• tegangan (power supply)

  

Langkah langkah tutorial arduino seven segment Sebagai Berikut :

• pasang seven segment pada project board
• atur kabel jumper dengan susunan sebagai berikut

Arduino Pin	7 Segment Pin Connection
2	7 (A)
3	6 (B)
4	4 (C)
5	2 (D)
6	1 (E)
7	9 (F)
8	10 (G)
9	5 (DP)

• pada percobaan kali ini kami menggunakan seven segment common katoda, maka kaki common dihubungkan dengan ground (-). 
• masukkan Skrip berikut di arduino software 

// www.arduino.web.id
// urut dari 0 - 9
// untuk 7segment common katoda, jika menggunakan common Anoda, silahkan dganti "1" dengan "0"
