Based on AT89C51 single chip computer, a rush answerer is designed and manufactured. The specific requirements are as follows:
1. Designing an intelligence contest answering machine, which can be attended by 8 competitors at the same time, numbered 1, 2, 3, 4, 5, 6, 7 and 8, each with a button.
2. A key is used as the master switch of the host, which is used to clear the zero of the control system and start the rush response.
3. After the answering machine starts, the digital tube counts down 10 seconds. If a player presses the answering button and displays the player's number on the LED digital tube, the light is on and accompanied by sound prompts. After the countdown is completed, the competitor can't rush to answer. When someone rushes to answer successfully, other competitors are forbidden to rush to answer. The number of the first competitor is kept until the host clears the system.
