electronic quiz table using 8085
This project can be used in Quiz competitions. The circuit is based on Microprocessor. Simultaneously five players can participate in this game. It has five separate LED s to indicate who has pressed the key and it also display the number on the seven segment display of the microprocessor kit. The Reset switch is used to reset all the switches and the circuit will get ready for the next round. The above system is monitored and controlled by the 8 bit microprocessor 8085A and using the Ports of 8255. The Microprocessor continuously monitors the five switches and if any one of the switch is pressed then it latches the switch and the microprocessor switch on the corresponding LED and display the number in the seven segment switch. A Buzzer sound is also produced to indicate that some one has pressed any one of the Switch.
