DESCRIPTION

Compose a tiny tune with the new TinyPiano! Built around the ATtiny841 microcontroller, this product features 9 capacitive touch sensors, 10 pre-loaded Nokia style ringtones, a loud magnetic buzzer, and simple coin cell power. Seven of the capacitive touch sensors are piano keys and play different pitches. On either side of the keyboard is a function touch pad. Touching the lower pad while playing the keys will result in a lower octave. The high pad will give you a higher octave. Touching both function keys at the same time will play one of 10 randomly selected ringtones!
