Laser Harp MIDI Controller with Musical Articulations ECE 445 FALL 2014: Laser Harp MIDI Controller with Musical Articulations Group #4: Hanze Tu, Yingxi Hai

Introduction A visually appealing music instrument An innovative way to play music

Objectives Wanted to incorporate: -Ability to play different tones -Plucking at slower speeds result in softer sound -Different audio filters and effects

Accelerometer - Data Mapping Input: converted acceleration value in g Output velocity range: 25-127 Map 0-1g to 25-85 Map 1.01-4g to 86-127 Map >4g to 127

Accelerometer - Data Mapping

Conclusions and Further Work Accelerometer tested and verified Integrate accelerometer with microcontroller Test distance sensor and photodiodes Future work: vibration motor for tactile feedback
