Self-contained project code for the "Godot Isn't Just for Games" series: Arduino sketches, the Python serial<->UDP bridge, and the Godot 4 projects, one folder per article.
Godot + Arduino — blog project code
Companion code for the "Godot Isn't Just for Games" series on the Codebycandle blog — using the Godot 4 game engine as a hardware control panel for an Arduino Uno.
Each folder is a self-contained project for one article: the Arduino sketch, the Python serial↔UDP bridge, and the Godot project.
| Part | Article | Folder | What it does |
|---|---|---|---|
| 1 | Your First Arduino Round-Trip | godot-arduino-1-led-first-light/ |
A Godot button lights a real LED on D13, over a Python-to-UDP bridge. |
| 2 | A Live Joystick Dashboard (coming soon) | godot-arduino-2-joystick-dashboard/ |
A KY-023 joystick streams x,y,btn telemetry into a glowing Godot XY pad. |
The shape of it
Arduino <--USB serial--> bridge.py <--UDP 127.0.0.1--> Godot
Godot has no serial support, so a ~40-line Python bridge owns the COM port and relays each line over UDP on localhost, in both directions. See each part's README for wiring and run steps.
Requirements
- Arduino Uno (or compatible) + the Arduino IDE
- Python 3 with
pyserial(pip install pyserial) - Godot 4 (standard build — no GDExtension needed)
