🐍 Control Arduino boards using Python instead of C++! This repository contains all the code examples from our comprehensive tutorial on programming Arduino with Python using the PyFirmata library.
- Easier syntax than C++ for beginners
- Rapid prototyping and development
- Massive Python ecosystem for data analysis and web integration
- No C++ knowledge required - just upload Firmata once!
- ✅ Set up Python to communicate with Arduino
- ✅ Control LEDs, sensors, and servo motors
- ✅ Read analog and digital inputs
- ✅ Build real projects without writing C++ code
- ✅ Troubleshoot common issues
| Project | Description | Difficulty |
|---|---|---|
| LED Blink | Basic LED control with Python | Beginner |
| Button Read | Read button states in Python | Beginner |
| Sensor Reading | Read analog sensors with Python | Intermediate |
| PWM Control | Control LED brightness | Intermediate |
| Servo Control | Control servo motors with Python | Intermediate |
- Python 3.8-3.11 (recommended: Python 3.10)
- Arduino UNO or compatible board
- Arduino IDE for uploading Firmata
pip install pyfirmata
- Open Arduino IDE
- Go to File → Examples → Firmata → StandardFirmata
- Upload to your Arduino board
from pyfirmata import Arduino, util
import time
board = Arduino('COM8') # Change to your port
led_pin = board.get_pin('d:13:o')
while True:
led_pin.write(1)
time.sleep(1)
led_pin.write(0)
time.sleep(1)
