The first person to press the key is granted the opportunity to answer the question.<\/p>\n\n\n\n<p>In this setup, an Arduino Mega continuously monitors eight push buttons, each representing one of the eight candidates. The system identifies which button is pressed first. The button number of the candidate who presses the button first is displayed on an LED screen to indicate the winner. Pressing the reset button built into the Arduino Mega board returns the display to its initial state, ready for the next round.<\/p>\n\n\n\n<p>The P10 display is connected to the Arduino Mega via SPI pins. Fig. 3 shows the P10 LED display and its pinouts for connection.<\/p>\n\n\n\n<div class=\"mepr_error\"><div class=\"prime-members\">\n<h4><strong>OOPS!
