Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah jam digital yang dilengkapi dengan kalender, alat ini menggunakan DMD led panel P10 sebagai media penampil jam dan kalendernya sehingga terlihat jelas meskipun dari kejauhan. alat ini menggunakan arduino uno dan RTC ds1307. untuk lebih jelasnya berikut adalah skema dan programnya.
