Jam Digital TM1637 dengan Pengaturan Waktu dan Alarm – Prototaip Arduino Nano

Komponen dan Perlengkapan

Tentang Proyek Ini

Ini adalah prototaip dari mekanisme pengaturan waktu dan alarm yang saya rencanakan untuk digunakan dalam proyek jam digital saya selanjutnya. Saya harap Anda menemukannya berguna. Jika Anda memikirkan perbaikan apa pun, beri tahu saya. Saya akan sangat senang memeriksa mereka dan potensial mengintegrasikannya ke dalam kode saya.
