A small Arduino Nano based Reaction Game

Arduino LED Reaction Game

This is a small game I made using an Arduino Nano for the class Physical Computing (IGME 470)
All code for this project can be found at this GitHub repository.

How to Play

• The point of the game is to press the button corresponding to the light that is currently lit.
• On my setup, the bottom button corresponds to the green LED, while the top button corresponds to the red LED.
• The two LEDs will light up for a random amount of time, independent from one another.
• Pressing the correct button while the LED is lit up will add 1 point to an internal counter.
• Pressing a button while the corresponding LED is not lit up, will subtract 1 point.
• There is a buzzer attached that will make sounds depending on success/failure.
• By default, the win condition is to get 20 points.
• Upon reaching the 20th point, a small jingle will play, signifying you won the game and then restarting.
• If desired, a custom win condition can be set by holding both buttons down while the Arduino is powering on.
• Both LEDs will turn on, telling you that you're now in win condition selection mode.
• Pressing the button that corresponds to the green LED will increment the score by 1, starting at 1.
• When the desired win condition is reached, pressing the button corresponding to the red LED will start the game.
• In addition, information such as the current score, winning score, and winning score selection is printed to the Serial monitor for ease of use. 

Video Playthrough

Below is a short playthrough of two rounds of the standard 20 point mode. I then show off the win condition selector mode by choosing a goal of 4 points.
