Scalability of Circuit System

It should be noted that for this prototype we utilized parallel circuits, for each hardware component, connected to individual pins in the Arduino board. However, for a full size gameroom the number of pin connections to the Arduino should be minimized since there’s a limited amount of available pins in the Arduino board. Therefore, an increase in the scalability of this platform can be achieved by implementing sophisticated communication protocols like I2C (shown in the figure below) which minimizes the input pin connections to only 2 for up to 127 different hardware components.
