Story

We were inspired to make a trivia game because we wanted something fun. How It Works: so when you first plug it in it'll look the same. Start out by making some trivia cards. Have someone read the questions. The first person to press the buzzer will make the light light up. The left buzzer represents the blue light, and the right light represents the green light. The first person to press the button will activate the light and deactivate the other light so the other one will not turn on. The piezo will also make a sound when someone presses their buzzer.
