Tutorial: How to use R140 Motor 3V 5V

This motor is ideal for small projects that require movement. Useful for beginners and intermediate makers.

What you need

• R140 Motor 3V 5V
• Arduino or compatible microcontroller
• Pull-up resistor (10kΩ)
• Connection cables

Steps

1. 1. Connect the motor to the microcontroller using the cables.
2. 2. Check the datasheet for power supply specifications.
3. 3. Connect the pull-up resistor between VCC and GND.
4. 4. Configure the motor pins in the Arduino code.
5. 5. Write the command `motore.attach(pin)` to assign the pin.
6. 6. Use `motore.write(1)` to start the motor forward.
7. 7. Use `motore.write(0)` to stop the motor.
8. 8. Check the operation by monitoring the motor.

Example code

motore.attach(9); motore.write(1); delay(2000); motore.write(0);

Mini project

Build a robot that moves forward and backward for 2 seconds.

Common mistakes

• Forget to connect the pull-up resistor.
• Use incorrect pins in the code.
• Power the motor with incompatible voltages (other than 3V or 5V).
• Do not use sufficient delay to observe the movement.

Recommended accessories

• Arduino Uno
• 10kΩ pull-up resistor
• Connection cables
• Electrical protection

Frequently asked questions
