tyler parker 28339f198f Add double-click bridge launchers; document ledtest + launchers in READMEs

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: 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.

arduino/
  JoystickBridge/JoystickBridge.ino    # streams "x,y,btn" + still drives the LED
  bridge/bridge.py                     # same serial <-> UDP relay as Part 1
  bridge/start-bridge.bat              # Windows: double-click to start the bridge
  bridge/start-bridge.command          # macOS/Linux: double-click (or ./) to start the bridge
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

Flash arduino/JoystickBridge/JoystickBridge.ino to the Uno.
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.
Godot: open godot/ArduinoGodot/ in Godot 4 and press Play — move the stick.
