Choose Arduino When:
- You are an absolute beginner in electronics
- Your project involves sensors, LEDs, motors, or displays
- You need low power consumption (battery-powered projects)
- Real-time hardware control is required
Choose Raspberry Pi When:
- You need a full Linux operating system
- Your project requires internet, camera, or multimedia
- You want to run Python scripts or AI/ML models
- Multiple complex peripherals need to run simultaneously
Our Recommendation for Beginners
Start with Arduino — it is simpler, cheaper, and teaches core electronics and programming concepts. Then progress to NodeMCU/ESP8266 for WiFi IoT projects. Graduate to Raspberry Pi for advanced AI/vision projects.
