🔧 Integration Ideas (Arduino / Raspberry Pi)

• Pair with a mini DC motor and a rectifier/regulator module to generate and measure voltage and current.
• Use a motor driver module (e.g., L298N, DRV8833) with an Arduino or Raspberry Pi for controlled fan experiments.
• Measure generated voltage using a microcontroller ADC and log data for wind-speed vs. output studies.

💡 Mounting Tips

• Verify your motor shaft is approximately 2 mm for a proper press-fit.
• For generator experiments, couple to a mini DC motor and add a simple rectifier module before measuring voltage.
• Intended for educational and low-power use; motor not included.
