Our tool is a simple ukulele, the instrument of choice among those who want to pursue a hobby in music, yet don't have the money to shell out on a full guitar or piano. With such versatility, we saw the ukulele as an opportunity to shift the statistic and increase people's opportunities to play music. The plan was to place LED's in the fretboard of the ukulele that would indicate where the user should place their fingers in order to strum the proper chord. Then using the Arduino IDE and some piezo-sensors, the ukulele would be able to recognize chords and check to see if they were played correctly.Toying with the intersections of Arduino, SolidWorks, and our own creativity, we constructed a ukulele using laser-cut wood and 3D-printed plastic parts. We soldered LEDs to the fretboard, attached commercial ukulele strings, and connected it to a circuit board made of breadboards, jumper cables, and integrated circuits. Our final product is something that not only innovates along the intersection of music and engineering but can also be used in the real world to help real people garnering positive feedback from users. Although this is still just an initial prototype, there are many enhancements that could come from this idea, including additional methods to input chords, preset songs, and even a more acoustically accurate instrument that could come in various sizes.
