Ketikkan Ptogram diatas pada Aarduino IDE kalian, hubungkan Board arduino dengan Komputer menggunakan USB Arduino kemudian upload program ke Board Arduino. Pastikan proses upload selesai dan berhasil.

Setelah Program Selesai di Upload silahkan Pencet pada kedua Push Button secara bergantian dan lihatlah yang terjadi pada 7 Segment.

Sampai disini dulu tutorial Arduino UNO kali ini ya sahabat Indobot. Setelah berhasil mencoba tutorial ini silahkan pahami programnya dan kembangkan sesuai keinginan kalian. Sampai ketemu lagi di tutorial selanjutnya….
