Aplikasi Mikrokontroller 001 “Traffic light 3 arah dengan atmega8535”

Posted on by

Pada aplikasi ini saya mempergunakan atmega8535 sebagai mikrokontroller utama atau main controller nya ,, rangkaiannya cukup simple dengan mempergunakan 9 buah led sebagai prototype. Dan led tersebut akan menyala dengan active low ( jika diberi logika 0).

Timernya masih menggunakan sistem delay (waktu tunggu) dan untuk waktunya bisa dimodifikasi sesuai dengan keinginan dengan mengubah nilai _delay_ms(“waktutunggu”);.

Berikut komponen yang dibutuhkan :

  • 1 ic microcontroller atmega8535
  • 1 crystal 11.0592 MHz
  • 2 Capasitor 22nF
  • 1 Push button (sbg tombol reset)
  • 1 Resistor 10K
  • 1 Capasitor 10uF
  • 9 Resistor 330 Ohm
  • 3 Led warna merah
  • 3 Led warna kuning
  • 3 Led warna hijau
  • Catu daya (adaptor 5v)

Dan ini program bahasa C dengan AVR studio4 :

Video tutorialnya akan saya post pada blog selanjutnya. So ditunggu ya sobat.

Semoga bermanfaat ..
