Project-Specific Success Criteria 1. An ability to respond to touch by producing sound and emitting light. 2. An ability to memorize past note events and to play the selected tones in a sequence set by the user. 3. An ability to utilize an accelerometer to detect the inclination and direction of the device so that the pitch and tempo of music can be changed. 4. An ability to load various sound effects such as guitar, piano and drum beats from the internal memory of the microcontroller and to play out the sound. 5. An ability to send the musical tones out to a computer through MIDI-USB protocol to be saved as a file.
