PyDuino is a Python-to-Arduino transpiler and uploader. Write Arduino sketches in Python, automatically convert them to C++ .ino files, and upload to your Arduino board.

• Convert C++ headers to Python stubs (.py) 📝
• Transpile Python scripts to Arduino .ino files ⚙️
• Auto-generate setup() and loop() if missing 🔄
• Upload sketches directly to Arduino from Python 🚀
• Detect Arduino headers in Python files 🔍
• List available COM ports 📡
• Support for multiple function overloads and basic Python-to-C++ expressions ✨
• Your comments are retained! 🗣️

1. Clone or download the PyDuino repo.
2. Ensure that Python 3.11+ is installed.
3. Run build.bat.
4. Enjoy!
5. Examples at: https://github.com/pro-grammer-SD/pyduino_seperate_tests/

python main.py create <project_name>

Creates a folder with main.py and lib/ for headers.

python main.py convert-header <header_file> [--libclang <path_to_libclang>] # or you can skip --libclang by default!

Generates Python .py stubs in lib/.

python main.py to-ino <python_file> [--auto-loop]

Generates .ino file. --auto-loop will call all functions in loop() automatically.

python main.py setupavr

Installs the Arduino AVR core using arduino-cli.

python main.py upload <python_file> [--auto-loop] [--port <COM>] [--list-ports] [--fqbn <fqbn>]

• --auto-loop: auto-call functions in loop()
• --port: specify COM port
• --list-ports: show available boards
• --fqbn: Fully Qualified Board Name (default: arduino:avr:uno)

• Converts Python for, while, if, and function definitions to Arduino C++.
• Supports arithmetic, boolean, comparison, and unary operations.
• Detects headers from from lib.<header> import lines.

• Upload logs are stored in <sketch_dir>/logs/YYYYMMDD_HHMMSS.log

# Create a project
python main.py create MyProject

# Convert a header
python main.py convert-header lib/CheapStepper.h

# Transpile Python to .ino
python main.py to-ino main.py --auto-loop

# List ports
python main.py upload main.py --list-ports

# Upload to board
python main.py upload main.py --port COM3 --fqbn arduino:avr:uno

#💡 Tip: the port is auto-detected, so generally in normal cases you don't need to specify it. Only use it if you really need to.

• 🔒 PyDuino currently supports Windows only. It would be great if you could help me to port it to other operating systems.
• 😄 Also, feel free to help me improve this library, block-by-block! PRs are always welcome and openly supported!
