MEMBUAT JAM DIGITAL (SIMULASI)

Salam Ilmu Pengetahuan

Kesempatan kali ini kami akan menjelaskan tentang jam digital memenuhi salah satu request dari pembaca kami. Tak usah berbasa-basi lagi. Jam digital membutuhkan sebuah perangkat digital yaitu IC yang tugasnya menghitung waktu. IC tersebut dinamakan RTC atau Real Time Clock. Banyak sekali varian RTC di pasaran namun yang akan kita gunakan adalah DS1307 kebetulan librarynya sudah bawaan di Codevision AVR. Tutorial ini masih berbentuk simulasi karena kami masih memfokuskan finansial pada segmen lain.

Alat

1. PC atau Laptop
2. Software ISIS Proteus
3. Software Codevision AVR / CV AVR

Komponen

1. ATMega 16
2. RTC DS1307
3. LCD 16×2
4. Crystal 32,768 kHz
5. R 10K
6. R 10K
7. Minimum System
