thanks everyone (and i have deleted the other posts— sorry!)
i'm using a LDR to turn the LED on without light
and the LED will trigger the Servo Motor to a certain degree of angle.
since i cannot find much information with what i originally wanted to do with the sound,
i've decided to get a Waveshield and SD/MMC card to play the sound from the library as the motor moves.
Hopefully it will work.. and arrive in time!
