For my final I will be making a arm gauntlet made from eva foam, velcro straps, and a led touch screen display. I will be assembling the pieces of the foam separately from cut outs from outline drawings that I will create. I will assemble the pieces in order then super glue the pieces together on the length of my arm. The touch screen will be mounted on the Arduino and placed in the center of the foam design in the socket that will be cut out. The code will be used from the touch screen creator to modify the led screen for designs.
