Drummy Introduction Drummy is a portable musical instrument incorporating a drum sequencer that is extremely simple and easy to use. It is designed as a mini controller for kids to get familiar with basic tempo in drumming and develop a better sense of rhythm. It has a slick and clean look with comfortable light-emitting silicone buttons that can easily catch the kids' attention. Team Members Siyuan Hu: CS Major NYU '17 Zack Kimelheim: CS/French Major NYU '18 Main Parts 16 LEDs 4 potentiometers 4 decorative caps for potentiometers 1 Leonardo microcontroller board 1 Trellis board a few wires for soldering 3D-Printing for Drummy We decided to 3D print the enclosure case for our final project. There are 4 design pieces (base, frame, tray, lid) that house the components and keep them secured with machine screws. The Arduino is mounted to the bottom cover with 4 screws. 4 potentiometers are mounted to the top panel and secured in place.
