LED mounted on paper

With our upcoming project being a wearable project, having the ability to sew circuits into clothing would be the optimal way to prototype. Currently, I've not got any spare fabric that's think enough for my sewing needles so I decided to test ideas using paper. The way i found works the best to attach an LED to this "fabric" is to poke both leads through, bend at 90 degree away from each other, wrap steamed wire around the leads, and solder for a good connection. The leads can then be trimmed to size at this point. The LED can then be used in any way that it normally could be used in a circuit.

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.
