My Controller(Kyle Spence)

 For my controller I went with a simple motion control setup for Super Mario Brothers classic. In this game the controls are WASD and with the tilt of the controller the titular character moves to the right or left. If the CPE is moved Up or Down, Mario jumps and squats. I went with motion controls to simulate the innovation of the Wii remote that came decades later from Nintendo. I wanted to give a level of immersion for the player by simply taking away the need for someone to constantly press the arrow keys on the original NES controller, I thought that by giving motion the player would enjoy moving the character and maybe get rid of some frustrations from the physical stress that may be caused.  I simply used a familiar box to house all the electronics within them even though there are better housing equipment. There’s even a potentiometer that controls Mario’s sprint/fire ball off to the side. So nothing really too complicated, I wanted to simply use a twist because while the player is continuously moving the controller they also can manage the need to attack the opposing enemies. I had trouble figuring out the  bluetooth within the CPE with this particular project, and the design was also last minute as well. The electronics also were kinda of complicated because I was tossing so many design back and forth, plus getting the materials was also kind of difficult. The signature JUMP that Mario has was interesting because I had to constantly figure out what the delay and the orientation of the CPE needed to be to successfully do different jump heights.
