REACTION TIMER
[attachment=32990]
INTRODUCTION:
Basic concept behind this PLE was to design a system by which it is possible to measure human’s reaction time. Human's interest in determining or knowing “Who is the Fastest?” goes back to before the Olympics. With the advent of microprocessors, there have been a large number of games capable of being played by one or more players, and in which the microprocessor causes the generation of an action and the player attempts to respond to this action. However no games have been developed that are based on the measurement of more than one player's reaction time.
This game is very simple &interesting. We start the game by switching ON ready switch after the system is powered on.As soon as westart the game,LED (Yellow) glowsand one have to press a switch corresponding to it as fast as possible to see your reaction time. It will stop the internal timer of microcontroller and then display the time took by that person to respond to glowing of LED on LCD.
This reaction timer that may be used in a game of skill by a solitary player or by a team. Players may compete to beat a best time and may compete in a competitive “head-to-head” competition or tournament. This system can be improved to the electronic reaction timer game that controls the interaction between one or more participants, or which can be played against the machine itself.
This electronic reaction timer game that measures and displays reaction times measured in milliseconds. This PLE provides an electronic reaction timer game device that provides an automatic sequence of events that must be responded to by one or more participants.
WORKING:-
The above fig. shows the circuit diagram of reaction timer. It consist of microcontroller AT89S52, one input switch for user, 16x2 LCD, and one yellow LED.
When the game starts, LCD shows the title as “ REACTION TIMER “. After some random time yellow LED glows, and the user pushes the switch as per his response. The time interval between glow of LED and push of the switch gets displayed on LCD.
The program for the reaction timer is written in C language using Keil compiler. The Keil compiler is IDE which provide simulation for the program to test the logic in the program. This compiler includes all features of microcontroller. It is actually designed for the development of projects based on 8051 microcontroller.
It includes all peripherals such as timers, interrupts, I/O ports, etc.
OBSERVATIONS:-
When the game starts, message “REACTION TIMER” gets displayed.
After random period of time for user, yellow LED glows and till the switch is pressed corresponding to it, the LED remains ON.As soon as the switch is pressed yellow LED turns OFF and the response time gets displayed on the LCD in ms. But if the switch is not pressed within 10 sec then yellow LED turns OFF and message “TIME OUT” gets displayed on the LCD.
