+# 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
+
+```
+arduino/
+  JoystickBridge/JoystickBridge.ino   # streams "x,y,btn" + still drives the LED
+  bridge/bridge.py                    # same serial <-> UDP relay as Part 1
+godot/
+  ArduinoGodot/                       # Godot 4 project: XY pad + dot + LED button
+```
+
+## 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:** `python arduino/bridge/bridge.py` (leave running).
+3. **Godot:** open `godot/ArduinoGodot/` in Godot 4 and press Play — move the stick.
