Counter Up dan Counter Down dengan Display 7 Segment 4 Digit With Arduino Uno

Proyek Counter Up dan Counter Down dengan Display 7 Segment 4 Digit With Arduino Uno ini cocok untuk pemula yang sedang belajar pemrograman arduino. Disini pemula bisa belajar bagaimana menggunakan input berupa tombol tact switch yang diolah oleh arduino sehingga bisa menampilkan Angka pada 7 segment. Setelah belajar proyek ini, anda dapat mengembangkannya sesuai dengan keinginan anda.

Kebutuhan Hardware :
1. Arduino Uno
2. Tact Switch
3. 7 Segement Common Anoda 4 Digit

Untuk Pembelian Komponen bisa BELI DISINI.

Berikut ini adalah Schematicnya :

Setelah terkoneksi dengan baik silahkan upload sketch dibawah ini :
