Binary Conversion to Sound????

Essentially what I want to do (in laymans terms) is:

  • Write a message or use some text
  • Convert is into binary code (using some online converter or something)
  • send the binary cod to the arduino (maybe through serial connection (the monitor) or somethign like that
  • Have the arduino take the binary code and convert it to sound that can be output on one of the pins (so I can record it into an external device.
  • I also want to do the same in reverse but this is the main process for now.
