8 Candidate Quiz Buzzer Using 8051 Microcontroller At89c51 Pdf
The proposed 8 Candidate Quiz Buzzer design is used in quiz competition when they use buzzer for opting their turn. The proposed design is a microcontroller (AT89C51) based design and we use an AT89C51 microcontroller which belong s to the family of 8051 microcontrollers. In this paper we will see how the circuit design is made and how the buzzer works and displays the information on the screen. Brief on the 8 Candidate Quiz Buzzer working model and design: The AT89C51 microcontroller is a 40 pin package in which 32 pins can be used for input and output purposes. We use 8 switches and they are connected individually to port1 pins and we make a serial line for all the 8 switches so that they can be connected to a buzzer and when any switch is presses a buzzer is blown. We use a seven segment display to display the information of the switch which is presses. The code for this application is written in such a way that when any input switch is presses the corresponding switch number is displayed in the LCD screen.
This quiz buzzer disables the other inputs as soon as the first buzzer is pressed. This quiz buzzer can be used for a maximum of eight teams. It is built around 8051 microcontroller ( AT89C51 ). Using AT89c51 microcontroller. A prototype is designed considering the various loads of the college and a priority wise load switching is carried out by the microcontroller in order to maintain the desired maximum demand.
