Make a reaction timber game for two with Arduino. via instructables
Find how fast your reflexes are using this fun game called ‘Reaction Timer’ that can be made easily using arduino. The main aim of this game is to press a button as soon as possible when you’re asked to do so. This is a two player game so two players compete against each other and the one who presses the button in lesser time wins. But both of the players don’t have to play simultaneously. Each player has a separate chance when he is asked to press the button in a random time.
Well, this instructable not only tells you how to play the game but also how to make the game. The main setup of this game is an arduino connected to a liquid crystal display (LCD), a button, three LEDs and a microbuzzer. The leds and the buzzer just help you to press the button more early. First the game asks player 1 to get ready then a countdown from 3 is displayed and the leds lit one by one. When the countdown reaches 1, the arduino pauses for sometime confusing the player. Then between a random delay of 5 to 10 seconds it switches on the green led and prints ‘go!!!’ on LCD. At this time you have to press the button. But you just can’t immediately press it as it takes some time for the message to reach the brain and to co-ordinate your hands to press the button. On your pressing the button, it displays the time taken by you to press it in milliseconds or your reaction time, in plain words. If you don’t press it at all, it waits for two seconds then displays your reaction time as 2000 milliseconds. The same is repeated for player 2. After all that it finally displays the result that which player won the game or if it is a tie.
The project can be made easily in two hours so this can be a good weekend project. Making it breadboard would save time. It can also be a good project for beginners who are new to arduino. They would learn a lot about printing something on liquid crystal display.
Rules: The rules of the game are simple-
1. Each player will get a separate turn.
2. Player 1’s turn will come first.
3. He has to press the button on fourth beep, when the green led glows or the LCD prints ‘Go!!’. All these things happen simultaneously.
4. Each player can press the button only once.
5. The player with lower reaction time wins.
