This board was created to add sounds to my robots. By using a graphite pencil a poster board along with a Makey Makey you can create an interactive surface with 16 touch points.

Supplies

Makey Makey Classic, Poster Board, Paper, Graphite Pencil, Glue, Green Paint, 16 Alligator cables, 6 Jumper Wires, Un-Insulated Wire, Small Brass Picture Hangers, Ruler

Step 1: Setup and Design the Board Layout

Create a pattern on the poster board that you have selected to use for your project.
Using your graphite pencil draw heavy dark lines that extend to the end of your board. In this step, it is important that the lines do not touch each other.

Using a flat surface and a ruler helps create straight solid lines.

Step 2: Connect Makey Makey to the Board

Connect your alligator clips to the lines on your board and back to the Makey Makey.
Connect Jumper wires to the alligator cables for a easy connection coming out of the black standoff's that are on the back of the Makey Makey

Step 3: Scratch

Setup your sounds to each one of you lines connected to the Makey Makey
Remap you Makey Makey to modify the key and mouse settings on the board.

Step 4: Be Creative

I used a doodle bot and a soup mixer to activate the sounds on my board.
When you have what you want to use for your prop just make sure that the bottom of the surface has a conductive material and all points touching the board are connect together.
Connect a alagator wire from earth to your prop to complete the circuit when it touches the line on the board.
