Mariano Ulibarri and Elias Gonzales, Graduate Students in the Media Arts and Technology program at New Mexico Highlands University in Las Vegas, New Mexico have made an amazing project using Bare Paint and the Arduino Leonardo.
Given an assignment of constructing an unconventional keyboard that would utilize the Arduino Leonardo and its keyboard library. The prototype ouija keyboard was constructed in about a week and was programmed with the ability to type 5 characters: Y, E, S, N, O.
They used a 156 line screen to print a 10" x 15" piece of wood with Bare Paint to use as an interface. To find out more about their projects check out their website at http://helloleo.us/
