Membuat ETU (Engine Telegraph Unit) Menggunakan Mikrokontroller dan Bascom AVR (Interrupt serial UART) Master - Slave

Membuat ETU (Engine Telegraph Unit) Menggunakan Mikrokontroller dan Bascom AVR (Interrupt serial UART) Master - Slave

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana membuat sebuah ETU (Engine Telegraph Unit) yang biasanya difungsikan pada kapal untuk memerintahkan kepada abk kapal untuk melakukan sesuatu yang jaraknya jauh atau beda ruangan, jadi dari control room dapat memerintahkan abk yang berada pada posisinya untuk mengerjakan sesuatu sesuai dengan perintah pada ETU. disini yang dipakai hanya 3 buah push button, 3 buah led dan satu buzzer pada master, kemudian pada slave menggunakan 3 buah led, 2 push button dan satu buzzer. untuk lebih jelasnya berikut adalah komponen dan programnya.

a. Minimum Sistem ATMega

b. LED 

c. Buzzer

d. Push Button

e. Program Bascom AVR Master
