Quiz Buzzer Using Microcontroller
Quiz Buzzer systems are commonly used in schools and colleges during competitions. The process involves giving priority to the person who presses the buzzer at the earliest. However, the problem arises with the conventional buzzer systems if the buttons are pressed simultaneously by two or more persons. In such cases, it is difficult to make a choice, and sometimes the decision can be biased with the human intervention. The quiz-buzzer system proposed here consists of 8 switches corresponding to eight teams. The output is displayed on the 7-segment display. The buzzer is also devised to give an alarm sound for an infinitesimally small duration of time.
Electronic Token Number Display
The electronic token-number-display system is designed to eliminate the problems of conventional queue system that is quite time consuming and inconvenient. Each person is assigned a token number and once their token is displayed, the person is supposed to get the task done. This system is used mainly in banks, hospitals, restaurants and many other public places.The system requires the user to type the number on the keyboard and press the button in order for the number to be displayed on the LCD screen. It is possible to serially increment and decrease the numbers from the present number. A short duration of sound is buzzed for every changing of a number.
