Restaurant Ordering System Using Arduino and Proteus
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang digunakan untuk melalukan order makanan minuman dan dessert. jadi alat ini hanyalah simulasi dengan menggunakan software proteus 7. jadi simulasi alat ini menggunakan 3 buah push button untuk memilih pilihan yang tersedia dan ada satu buah tombol untuk resetnya. untuk lebih jelasnya berikut adalah koding dan skemanya.
a. Skema Simulasi Alat
