Connection Guide
Wiring:
- Red wire: Connect to positive (+) terminal
- Blue/Black wire: Connect to negative (-) terminal
- Supply voltage: 1.5V to 3.7V DC
For microcontroller control:
- Use NPN transistor (2N2222 or BC547) to drive motor
- Add flyback diode (1N4148) across motor terminals
- Use PWM signal for variable vibration intensity
For direct Arduino control, use a transistor driver circuit
Add a resistor in series to limit current if needed
Do not exceed 3.7V supply voltage
Avoid pulling on wires as they can break easily
Troubleshooting
Motor not vibrating:
- Check voltage supply is 1.5V to 3.7V
- Verify polarity (red to positive, blue to negative)
- Avoid loose connections
Weak vibration:
- Increase voltage to 3V for full speed
- Check battery voltage level
- Ensure motor is securely mounted
Motor stuck:
- Try sweeping a strong magnet across the motor body
- Tap gently on a hard surface to free lubricant
- Some units may require initial activation
