This project was an expansion from my interactive project. So I made a couple of changes, instead of using and LCD display board I used an OLED display board to display the updates. So I got rid of the two buttons from m interactive project used to update the scores.Also added a bluetooth Arduino to connect to the Arduino Duo and the OLED. With the bluetooth Arduino you can change the scores through your phone as oppose to using buttons. But you also need to download the bluefruit app from your app store.
