This is a project about lights. I built an arduino based racing game involving smashing a button and racing to the end of an LED strip. There are added mechanics like gravity to make the game more exciting.
Shoutout to the inspiration for this project, [Open LED Race](https://create.arduino.cc/projecthub/gbarbarov/open-led-race-a0331a).

Step 1: Arduino and LED
### 1.1 Set up box
#### 1.1.1
Attach to your box: Arduino Mega, breadboard, relay, RJ45 plug, power supply plug
#### 1.1.2
Plug Arduino into breadboard (refer to wiring schematic).
#### 1.1.3
Plug relay into breadboard (refer to wiring schematic).
#### 1.1.4
RJ45 to breadboard, add resistors
Green = Back-up Data Line
Blue = Data Line
Orange = 5V
Brown = Ground
Add a 470 Ohm resistor on both data line (refer to wiring schematic).
#### 1.1.5
Plug power supply into breadboard, add 1000 uF capacitor.
### 1.2 Set up LED strip
#### 1.2.1 Build LED extension wire
About 6-9 feet in length.
Solder wire connections.
Red (5V) = Orange
Black (Ground) = Brown
Yellow (Data) = Blue
Green (Back-up Data) = Green
Use heat shrink.
#### 1.2.2 Tape LED wire leads
#### 1.2.3 Plug LED strip into RJ45 keystone.
### 1.3 Software: Turn on lights
See [`./code/step1-turnOnLights.ino`](./code/step1-turnOnLights.ino)
Step 2: Start Button
### 2.1
Saw can half an inch inch taller than your box.
### 2.2
Cut a hole for your arcade button.
Solder lead wires to start button.
### 2.3
Connect start button lead wires to breadboard, and connect breadboard to Arduino.
Add 470 oHm resistor for LED. Add 10k resistor for button.
### 2.4 Software: Moving Lights
See [`./code/step2-movingLights.ino`](./code/step2-movingLights.ino)
Step 3: Controllers
### 3.1 Connect controller breakout board to arduino
#### 3.1.1 First controller
This is the configuration for the first player controller. All wires should be connected to breakout board port `D`.
Controller breakout port wire configuration:
- Wire 1: +5 volt return from leg 2 of switch - Connect to an available terminal strip on breadboard - Connect a 10k ohm resistor from this terminal strip to ground. This ground reference helps avoid false positive readings.
- Wire 2: +5 volt going to leg 1 of switch - Connect to +5 volt power rail on breadboard
- Wire 3: Ground for button LED - Connect to -5 volt power rail on breadboard
- Wire 4: +5 volt signal for button LED - Connect to an available terminal strip on breadboard - Connect arduino to the opposing terminal strip - Connect the two terminal strips with a 470 ohm resistor
Player 1 button = pin 26
Player 1 LED = pin 27
#### 3.1.2 Second controller
Follow the steps for the first controller, except this time using breakout port `C`.
Player 2 button = pin 22
Player 2 LED = pin 23
### 3.2 Make an ethernet cable
About 6-9 feet in length.
### 3.2
Drill a hole in the bottom of the pill container.
### 3.3 Controller Top Assembly
#### 3.3.1
Cut a hole in the lid of the pill container for the arcade button.
#### 3.3.2
Solder lead wires for your arcade button.
#### 3.3.3
Put your arcade button into the lid of the pill container.
#### 3.3.4
Attach the RJ45 Female breakout on the other side of the lid.
### 3.4 Controller Bottom Assembly
Insert the ethernet cord into the bottom of the pill container, then tie a loose knot immediately below the end of the ethernet cord.
### 3.5 Controller Final Assembly
Plug ethernet into RJ45 Female breakout. Be careful when you close container not to bend button pins.
### 3.6 Repeat for second controller
### 3.7 Software: Player Controls
See [`./code/step3-playerControls.ino`](./code/step3-playerControls.ino)
Step 4: Audio
### 4.1 Plug DF Player into breadboard
Add capacitor and resistor.
### 4.2 Plug 3 watt speaker into breadboard
### 4.3 Download sounds on to Micro SD
>The folder name needs to be mp3, placed under the SD card root directory, and the mp3 file name needs to be 4 digits, for example, "0001.mp3", placed under the mp3 folder. If you want to name it in Both English and Chinese, you can add it after the number, for example, "0001hello.mp3" or "0001后来.mp3".
See [`./audio/](./audio).
### 4.4 Plug Micro SD into DF Player
### 4.5 Software: Audio
See [`./code/step4-audio.ino`](./code/step4-audio.ino)
Step 5: Gravity
### 5.1 Measure
Hang your LED strip up on a wall or something. Choose a place that makes sense for gravity to begin, for example where the light strip begins traveling vertically.
Measure how far from the end of the LED strip this location is. Calculate the index of the LED at this position by using the measured length, the total length of the strip, and the distance between LEDs.
### 5.2 Software: Gravity time
See [`./code/step5-gravity.ino`](./code/step5-gravity.ino)
Step 6: Final Software
Add a winner to the game.
See [`./code/step6-final.ino`](./code/step6-final.ino)
