Mission Description
Context: Your class is excited about a quiz competition. To make it fair and fun, build a Quiz Show Buzzer System that lets players answer questions by pressing a button, with the device showing who buzzed first.
Task: Create a setup with at least two input buttons (for two teams or players) connected to your Junkbot Core. Program logic to detect which button was pressed first. When a button is pressed, the system could light up an LED or display “Team A!” (or Team B) to indicate the first responder, and ignore the second button if it’s pressed shortly after. You might add a simple reset function (maybe shaking the device or pressing a “reset” button) to clear for the next question.
Expected Output: A two-player buzzer system for classroom quizzes. During a demo, when Team A presses their button, the device immediately flashes “Team A” on the screen (or lights A’s light) and locks out Team B’s input for that question. This ensures fair play in quiz games and gives students a taste of interactive electronics used in game shows
