Overview The project has been designed to draw a pong ball onto any flat surface using a digitally controlled laser projection platform. Explanation The game is named as Wall of Pong which brings the arcade pong game to the real world by projecting an image of the pong ball on any flat surface and allowing players to play the game with real paddles and establishing a large playing area. There are 3 components on which the laser platform if built around and these are the laser project platform, the handheld paddles, and the microcontroller. Using a rotating mirror, a laser beam is first projected. Due to slight off-axis mounting angle, the reflected beam will be circular which can be steered using two motors. The x-axis motion is controlled by one motor while the y-axis motion by the second motor. The orthogonal rotation of the mirror in independent axes is allowed by the mechanical mechanism known as gimbal. The operation of the gimbal will be controlled by the microcontroller so the ball would move around the playing field and have it bounce off virtual walls. The detection of the projected laser is handled by the microcontroller. Rest of the project
