Original price was: Rp313.000.Current price is: Rp300.500. Add to cart

Kit juga dapat dibeli di Tokopedia dan Shopee.

Kali ini kita akan mencoba membuat rangkaian Jam Digital, dimana fitur-fitur yang ada sebagai berikut :
1. Pengaturan Jam dan Menit pada #jamdigital
2. Pengaturan waktu AM / PM
3. Pengaturan tingkat kecerahan (brightness) dari pada #LCD1602
4. Angka display jam yang cukup besar karena 2 baris LCD 1602 digunakan + Bold Text.

Peralatan yang diperlukan sudah cukup pada kit diatas, sehingga kita langsung saja merakit rangkaian yang diperlukan sebagai berikut :

Script Arduino yang digunakan sebagai berikut :
