Tentang proyek ini

Saya membuat JAM Modul Matriks LED 8x8 yang dikembangkan oleh Adrian Jones. Waktu ditampilkan dengan menggulir dari kiri ke kanan, atau, di bawah kendali perangkat lunak, dari atas ke bawah. Setiap digit waktu berturut-turut meluncur dari sisi kanan dan ketika di tengah, berhenti sejenak dan sedikit cerah. Ini kemudian menggulir ke kiri sementara digit berikutnya di layar bergulir ke tampilan. Siklus berulang dengan jeda singkat antara tampilan yang berurutan.Untuk membalik vertikal "dari atas ke bawah" Anda harus mengubah :

static boolean top2bottom =false;

ke:

static boolean top2bottom =benar;

Seperti yang Anda lihat di komentar kode, banyak parameter dapat diubah, misalnya kecepatan gulir, jumlah baris kosong antar karakter, tampilan 12/24 jam, ms antar karakter, kecerahan dll.

Waktu dapat diatur dengan mudah menggunakan rotary encoder. Dioda dua warna menampilkan mode pengaturan (menit, jam, atau normal). Saya memasukkan jam ke dalam kotak yang terdiri dari dua bagian dasar sehingga akses ke bagian dalam kotak adalah sangat nyaman dan praktis.
