We built this project as part of Art of Engineering course, where we were supposed to create an ateri game with physical components. My group and I decided to build an ateri version of the Korean childrens game “Red light Green light”. Our game consisted of many moving parts to accommodate three players at the same time. Two of the three characters controlled by the players moved along threaded rods, and the third one was connect to a servo. This player would rotate the servo to catch the other two players while they were moving. Since it was a reflex game, precision became really important in our computations. We had make sure the buttons would function in correlation, with there being the same amount of delay for all three players. Thus this one project composed of two ardunios working together, process data from three buttons, and to conducting two DC motors as well as another servo motor at the same time.
