1. Introduction
This project is to design a laser, build, and demonstrate a laser beam reaction game to see how fast players can react to a sequence of visual cues. In this project, we created a rectangular 3 x 3 grid of Lamp: photo detector pairs. The middle detector pair will have a second lamp of a different color. The player will stand or sit at a distance of 8 feet or more from the game set. A laser pointer will be used to play the game. Whenever game is complete or whenever it is time to start a new game, the middle lamp that is a different color will be lit. The player will start the game by shining the laser at any of the 9 photo detectors. A random sequence of lamps will then be lit and the reaction time to “shoot” the light sensor adjacent to the lamp that is lit will be measured. After the target is hit, the lamp will go off. This will be repeated 8 times. After the 8th lamp goes off, the game is over and the total reaction time is to be displayed on a 7 segment display in seconds. Once the reaction time is displayed, the game should be restarted. The reaction time of the previous player should remain on the display until the following player completes playing the game.
2. Main idea
This project seems straight forward. Firstly, we need to generate one number of nine randomly. Then we need to visualize these random numbers by connecting with LED. And after so we need a counter to count the number till eight and stop the game and in the end display the total time cost with a 7-segment display.
3. Design outline
Basically, there are two major parts in our design
• Random lights generator
• Timer display circuit
• Lamp: photo detector pair
