start-bridge.bat (Windows) and start-bridge.command (macOS/Linux, +x) sit next to bridge.py in both parts so readers can start the bridge with a double-click. READMEs now cover the launchers and the ledtest.py debug path.

# 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.
|
|
|
|

## 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.
