Oxygen: Membuat Running LED (Seri Tutorial Micro controller)

Kali ini saya mencoba untuk menulis tutorial tentang Micro Controller menggunakan seri ATMega8535, memanfaatkan lampu LED yang menghasilkan tampilan nyala LED yang berurutan serta secara acak.

Siapkan komponen-komponenya sebagai berikut :

Micro Controller seri ATMega8535 1x

Switch / Saklar push button no/nc 1x

Crystal 12 MHz 1x

Capasitor 33pF 2x

PCB atau Project Board/Breadboard 1x

Software yang digunakan :

ISIS Proteus yang digunakan untuk membuat rangkaian simulasi.

BASCOM AVR : software bahasa pemrograman untuk membuat program gerakan LED.

Langkah pertama yaitu anda ketik lebih dahulu listing programnya seperti contoh di bawah ini
