Design and Build an Didactic Ukulele.

So, this instructable basically shows how you can make a didactic ukulele. To achieve this, a CNC and a 3D printer were used that manufactured the parts designed in Fusion 360.

1. Arduino nano
2. 220 ohm resistor (48)
3. Push button (44)
4. LEDs (44)
5. L293D Quadruple Half-H Driver (1)
6. Speaker
7. 7.4 to 11.1 V Battery

1. Screw M3 x 12 (40)
2. Nuts M3 (15)
3. Screw M2 x 8 (20)
4. Triplay .1 inch
5. 1 Kg PLA translucent

To better understand the idea here are some simple diagrams and tables of the Project

In this case it was chosen to have 7 frets and the single string. It was decided to have an LED and a button for each note and have buttons that turn on each of the notes.
