Liquid Crystal Display (LCD) 2x16

LCD adalah komponen yang dapat menampilkan huruf, angka, atau symbol lainya. LCD kita butuhkan untuk menampilkan nilai data yang akan kita proses. LCD yang kita pakai berukuran 2x16 (2 baris 16 kolom).

Berikut adalah rangkaian  LCD yang saya buat:

1. Komponen yang digunakan adalah atmega32, LCD 2x16, trimpot, button, terminal mode power dan ground, serta generator DC.

2. Setelah rangkaian tersusun, kemudian masuk ke software cvavr. 

3. Membuat codingan menyalakan LCD dan menampilkan huruf :

#include <mega32.h>

#include <delay.h>

// Alphanumeric LCD functions

#include <alcd.h>

void main(void)
