Membuat Jam Digital Menggunakan RTC DS1302 dan OLED LCD DISPLAY

Membuat Jam Digital Menggunakan RTC DS1302 dan OLED LCD DISPLAY

 

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara mengakses OLED LCD dan RTC DS1302 secara bersamaan, aplikasi dari alat ini yaitu untuk menampilkan jam dan tanggal pada lcd oled display dan juga bisa setting alarm sesuai yang diinginkan, jadi jika jam telah masuk pada zona alarm maka led atau buzzer akan menyala sehingga akan menandakan bahwa ada peringatan. untuk lebih jelasnya berikut adalah skema dan programnya.
