# Part 2 — A Live Joystick Dashboard

Code for *"Godot Isn't Just for Games: A Live Joystick Dashboard"* **(article coming soon).**

Builds on [Part 1](../godot-arduino-1-led-first-light): a 2-axis KY-023 joystick streams
its position up the same bridge into a Godot console — a glowing dot tracks the
stick across an XY pad in real time, with the LED button still working.

## Contents

```

  JoystickBridge/JoystickBridge.ino    # streams "x,y,btn" + still drives the LED

  bridge/start-bridge.bat              # Windows: double-click to start the bridge
  bridge/start-bridge.command          # macOS/Linux: double-click (or ./) to start the bridge

```

## Wiring (adds to Part 1)

KY-023 joystick: `+5V`→5V, `GND`→GND, `VRx`→A0, `VRy`→A1, `SW`→D2. Keep the
LED from Part 1 on D13.

## Run it

1. **Flash** `arduino/JoystickBridge/JoystickBridge.ino` to the Uno.
2. **Bridge:** double-click `arduino/bridge/start-bridge.bat` (Windows) / `arduino/bridge/start-bridge.command` (macOS), or run `python arduino/bridge/bridge.py`. Leave it running.
3. **Godot:** open `godot/ArduinoGodot/` in Godot 4 and press Play — move the stick.
