My idea is to create a volleyball game that allows users to play against a wall, bouncing the ball in circles to earn points all while trying to keep the ball up off the ground.
The arduino will consist of 6 sensors connected to it, aligned along the edge of the wall on the floor, pointing up and equally spaced. These sensors will detect anytime a ball bounces along the wall above the sensors. Then, there will be a projector behind the player. This will project a p5 sketch with sporadically appearing circles projected on the wall. As the player bounces/passes the ball into the circles, the sensors will detect an input and the player will score the point and make that circle disappear, and a new circle will appear, and so on. The goal is to get the most points in 60 seconds of play. The player is naturally penalized for dropping or losing the ball when they are forced to go and pick it up and return back to continue playing as they are on a timer. The player must stand behind a red tape line I will place a distance from the playing wall surface.
