Bilgisayarın LPT portunda kullanılan basit ledli devre (sadece led ve direnclerden oluşuyor) ve kontrol programı ile çeşitli efektler ya da vu metre yapılabiliyor WndLpt programı içinde hazır efektleri bulunduruyor eklentiler ile Winamp 5, WMP Windows Media Player, AIMP2 programlarını destekliyor.

 

 

Find motherboard's LPT port. Locate pin labels.

 

 

Check numbers.

 

 

Join LED to pins 2 and 18.

 

 

Now I can use WndLpt to control this LED.

 

 

^ Circuit diagram for 12 LEDs

I can directly connect up to 12 LEDs to the LPT port. It's very simple.

Some people like to connect only eight LEDs. It's not problem. The WndLpt program can manage any number of LEDs from 1 to 12.

 

It's time to make following circuit. We see face of motherboard's LPT port or DB25F Face (or DB25M Back side) on it.

Same circuit otherwise.

 

^ LEDs panel example

It is a good day to mount the LEDs on the panel.

I take any dark plastic surface and drill 12 holes on a circle.

 

 

I aspire to that view.
