Binary Conversion to Sound????

What kind of binary data? Just one bit (on or off)?

What kind of sound? Just some kind of tone?

Are you trying to make something like a telegraph or Morse code machine? If you want something that makes a tone when the input is 1, and no tone (or a different tone) when the input is 0, you can do that with an Arduino, but you don't really need a "brain chip" or programming for that. :wink:
