The intent of this project was to create a simple game using an Arduino that would be interactive and entertaining for kids. I remember the Cyclone arcade game being one of my favorite arcade games when I was younger, so I decided to replicate it. This is a very simple project that consists of an Arduino, string of individually adressable LEDs, and a push button.

The goal of the game is to stop the cycling light when it reaches the indicated (red) LED. If successful, the difficulty level will increase. If unsuccessful, the light cycle will restart at the current difficulty level.

This instructable was a huge resource for the core of my coding.

Step 1: Gather Supplies

Main Components:
- Arduino (I used an UNO)
- String of individually addressable LEDs (I used link)
- Push button (I used link)
- Printed circuit board (PCB) or breadboard
- Power Supply (I used two separate power supplies, you may get away with one if you are creative)
  - 5V 3A for LEDs
  - 9V 1A for Arduino

Framework:
- Electronics housing (I modified a wooden lamp fixture from Goodwill)
- LED housing (I modified your standard wall clock and drilled holes using the minute identifiers as hole markings. Use a wood clock if possible to make drilling easier.)
- Button housing (I used an elbow PVC pipe)

Tools / Other Materials:
- Spare wiring for your circuit
- 10K (pull-down resistor for switch) and 470 ohm (for data wire on LEDs) resistors
- Drill for creating holes to house your LEDs and and making any necessary holes in your fixture to pass wires through
- Soldering iron for soldering your circuit to a PCB
- Hot glue gun for securing the LEDs to your fixture
- Velcro or some means of securing the framework together
- Gaskets optional for holes drilled for wires to pass through

Step 2: Upload Code

Make sure you download and add the "FastLED" library

The core of the code (void loop) consists of two states: push button high (End Game) and push button low (Playing). Once the user presses the button, the LED address the light was stopped on is compared to the address of the center LED. If they are not the same, all the lights flash red twice and the current level restarts. If they are the same, cylon (FastLED library script) runs twice, the difficulty level increases, and playing resumes. Once the player beats the last level, cylon runs eighth times and the game restarts at level 1.

Step 3: Install in Fixture

I am not going to go into details in this section. There are a thousand different ways to go about this part and I think you should be creative to make it look how you like it. That being said, the clock was pretty convenient to use for housing the LEDs as it had minute indicators that I was able to use as drill markings. Also, the glass cover also lets me use this as a table.

The velcro was very useful as well for securing the LED fixture to the electronics housing fixture. I also used velcro on the Arduino. This made it very convenient for pulling the Arduino out if I ever want to modify the code.
