# Treeboard
![](https://hackatime-badge.hackclub.com/U092DB4LGMP/fidget) <br/>
A PCB that you can use to play minigames with 4 LEDs, 4 Cherry MX switches and a XIAO RP2040. 

## Game Modes
### Reaction Tester
- **Start**: Hold the top left button for 3 seconds (the LEDs will slowly light up as you hold it)
- **How to Play**: An LED will turn on within 5 seconds, and you have to press the corresponding button as fast as possible.
### Duel
- **Start**: Hold the top right button for 3 seconds (the LEDs will slowly light up as you hold it)
- **Players**
  - Player 1 uses the left buttons and LEDs
  - Player 2 uses the right buttons and LEDs
- **How to Play**
  - Hold the PCB horizontally
  - A mirrored LED pair will light up (eg the top left and top right)
  - The first person who presses that switch wins and whoever gets to 5 wins first has their LEDs flash as celebration
### Memory Game
- **Start**: Hold the bottom left button for 3 seconds (the LEDs will slowly light up as you hold it)
- **How to Play**
  - The LEDs flash a sequence that you have to exactly recreate with the buttons
  - Each time you succeed, the length of the sequence increases
  - If you fail, the LEDs turn on and off 2 times, and if you win, they turn on one by one.
### Binary
- **Start**: Hold the bottom right button for 3 seconds (the LEDs will slowly light up as you hold it)
- **How to Play**
  - The LEDs will show a binary number for 5 seconds
  - When they turn off, you have to input that value using the keyboard
    - Pressing the top left button adds 1
    - Pressing the top right button adds 5
    - Pressing the bottom left button subtracts 1
  - To submit your number, hold the bottom right button for 2 seconds
  - If you got it correct, the LEDs will all flash twice
  - If you got it wrong, they will flash one by one 2 times

## Other features
### Idle
After 30 seconds with no input, the LEDs will play a slow idle animation
