The Physical Implementation
The scoreboard is designed to keep scores that players gain from shooting balls at targets in the shooting gallery. When first enter the room, players will see a scoreboard and buttons on the wall light up blue. As the game starts, some buttons on the wall start to change color from blue to green. Once player press on these green buttons, they will change back to blue. When enough buttons are hit, balls will start to roll out from the shooting gallery. While some players need to remain in front of the wall to keep hitting the buttons, other players can start to gather balls from the shooting gallery and use the slingshot to shot at the moving targets on the wall. To prevent balls from being taken from the shoot gallery or players pulling on the slingshot too hard and hurt themselves, the shooting gallery will be confined in a cage or a net structure. Every time when a target is hit, the scoreboard will transition a bit from blue to yellow, meaning “Zeus” is one step closer to winning over “ Poseidon”. When the scoreboard turns completely yellow, it means the players have defeated "Poseidon".
The Electrical Implementation
The electronic design of the scoreboard has to allow it to transition from blue to yellow when targets are hit, and at the same time, if not enough targets are hit in a certain time period, the scoreboard has to show that scores are dropping by changing its color back to blue. The electronic design of the scoreboard is shown in the scheme in the right column. The essential component of the scoreboard is an Adafruit Neopixel LED strip. For the prototype, it will be connected to an Arduino microcontroller and a touch sensor that simulates the targets in the shooting gallery. When a target is hit, the microcontroller can detect a change in the voltage and translates this change to a signal to LED stipe to change one more LED from blue to yellow. The microcontroller will also keep track of the time, and if certain period of time has passed without any target being hit, one LED will be changed back to blue from yellow. To accentuate the lighting effect, the LED strip will be installed inside a LED wraparound covered by a layer acrylic light diffuser material. To emphasize the greek theme, greek patterns and symbols will be laser cut and stick on top of the diffuser layer.
