To make this instructable, you will need:
2. Presentation Board
3. Elmer Glue-All
4. Bare Conductive Touch Board
5. Conductive Fabric
6. Conductive Thread
Step 1: Construct the Projection Base
For folding the triangles, I followed this youtube tutorial:
Then I glued the triangles to the presentation board using Elmer's Glue-All(https://www.amazon.com/Elmers-Liquid-School-Glue-Washable/dp/B072J37ZZD/ref=sr_1_7?ie=UTF8&qid=1545111153&sr=8-7&keywords=elmer+glue+all)
Step 2: Make the Circuit!
For this step, I used Bare Conductive's touch board. To being the process, look for the "“Midi_interface_generic” code in the board's library, and upload the code through Arduino IDE.
For the circles, I used conductive fabric and conductive thread. Each piece of conductive fabric is connected to the pin on the touch board using conductive thread.
Step 3: Mapping the Projection
For projection mapping, I used Mad Mapper. After the previous step, you will be able to control Mad Mapper with your touch board. Then you will have to connect your computer to the projector and map the graphics you want. For the connection between touch board and Mad Mapper, I referenced this tutorial: https://www.bareconductive.com/make/touch-board-projection-mapping/
Step 4: Result!
After that, you will be able to control your projection mapping with your conductive fabric interface!
