It would be dead easy to do this with a pic microcontroller and the
PicBasic compiler. I think you could use one of the smallest PIC:s, a
cheap 8 pin device with built in oscillator.
In PicbBasic there is a command called "Sound" witch generates 127
differnet notes as PWM audio. You would only need two I/O-pins, one
input for the triggersignal and one out for the audio, and then make
every trigger on the input advance a counter that steps through the
notes in the melody.

This could probanly be done easily with basicstamp too.

  Hi List!

  i'm writting to you all for a suggestion/help .

  a friend of mine asked me to build a sort of keyboard for some circus
show he is putting on... he needs a sort of sensor that stays in the
floor, and once a ball touch it , it plays a note from Happy Birthday...
the sensor part isnt hard... but the musical part...its a different
story... any suggestions?

  thank you all!
