Notes

• The TinyPiano uses an ATtiny841 Microcontroller, but since it doesn't have USB support, it is not re-programmable without some serious hacking.
• The tunes programmed on each TinyPiano are randomly selected from a set of 200 tones during the manufacturing process. Most examples of TinyPiano are unique!
