The shared bridge shipped in both posts named Main.gd and
JoystickBridge.ino in its docstring and --baud help — so the part-1
(LED basics) download referenced files absent from its own project.
Neutralize the wording ("Godot", "the .ino sketch") so the same bridge
reads correctly in both downloads.
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.

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.
