Playing Tunes/Sounds Fx Nicta Ed1 Board


i'm currently learning how to use an arduino board in (C++) so im still a little sketchy

as our assignment we have to make a game using the board and the programming language and any of the board components, though its called paired programming so i'm in a group of 3 and they said i can do sound so i was like sweet no problem though......

i understand that you use the piezzo buzzer and that it uses frequency to make the sound though i can't read music other than guitar tabs so i need to somehow make a program that makes a laser sound with the frequencies and make like a cool intro sound, i have viewed tutorials on the net on playing tunes but how did they exactly convert happy birthday to frequency

so any help would be great
