Introduction: 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.

Supplies

  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

Step 1: Understand the Idea

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.

Step 2: Cut and Print the Parts.
