I have created a program in scratch for drawing, and am using a Makey Makey to use the program.

Supplies

Cardboard

Makey Makey

Device

Knife/Scissors

Brass Paper Fasteners

Sharpie

Glue Gun

Tin Foil

Alligator Clips

Step 1: Create the Scratch Program

Go to scratch.mit.edu, log into or create an account if you do not already have one, then create a new project.

Add the Pen extension to the project.

Then, create a sprite that is able to move around and can use the pen. As well as a way to change colors and brightness.

Step 2: Create the Things for the Makey Makey

Carve out a rectangular piece of cardboard with a scissor or knife
Insert the Brass Paper Fasteners through the cardboard
Tape the bottom of the Brass Paper Fasteners on the opposite side of the cardboard for stability
Insert more until you have enough for each button on your scratch program
Label them on the back side of what button they should be with a sharpie
Add a base for stability
Create something wearable that connects to the ground of the Makey Makey with something attached to you (such as a tin foil ring)

Step 3: The Makey Makey

Connect the Makey Makey to your device, then connect the bottom of the brass fasteners to the Makey Makey with alligator clips to the controls, and you should be done!
