To build a full-blown game controller, we only need to add a button to our breadboard. Figure 19, Game controller with accelerometer and pushbutton shows you how to do it. (Please double-check the pin labels on your breakout board!)
That’s how it looks inside a typical modern game controller. We won’t build a fancy housing for the controller, but we still should think about ergonomics for a moment.
