NEC Protocol IR (Infrared) Remote Control

Hello friends,
I am working in a scoreboard project and i am planning to control it using IR communication.
I need a IR transmitting Remote with 5 buttons in it.
I find a link in google with my needs suited, but its a design with pic micro controller. I am an Arduino guy, so can anyone point me to a design a same circuit which uses Arduino for controlling the IR Transmitter. I don't need the IR Receiver design. Since already built a IR receiver circuit and after encoded the values from my Tv remote, i can control my scoreboard using my Tv and its working like a charm.
