The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently.

Do I need a motor shield for Arduino?
You don’ t need this shield to drive servo motors, they have their own controller, you need just a 5V power line, GND and digital output pin to generate a PWM and that’s it. Usually Arduino has enough power to drive servo motors. This shield you are talking about is used for DC (direct current) and stepper motor.
What is the use of motor shield in Arduino?
The Arduino Motor Shield allows you to easily control motor direction and speed using an Arduino. By allowing you to simply address Arduino pins, it makes it very simple to incorporate a motor into your project. It also allows you to be able to power a motor with a separate power supply of up to 12v.
What is a motor shield used for?
Overview. The Arduino Motor Shield is a shield that lets you control various loads that a typical Arduino pin cannot drive. The motor shield has quite a few features such as current measuring and the ability to drive a single stepper motor.
What are the difference of Arduino motor and Arduino Motor Shield?
A motor driver is a chip that drives motors. A motor shield is a circuit board with connections on it that contains a motor driver chip that drives motors.
How does Arduino shield work?
Shields are pieces of hardware that sit on top of your Arduino, often to give it a specific purpose. For example, you can use a shield to make it easier to connect and control motors or even to turn your Arduino into something as complex as a mobile phone.
Which motor driver is best?
10 Best Motor Drivers For Arduino

How do you power an Arduino with a motor shield?
If you would like to have a single DC power supply for the Arduino and motors, simply plug it into the DC jack on the Arduino or the 2-pin PWR_EXT block on the shield. Place the power jumper on the motor shield. If you have a Diecimila Arduino, set the Arduino power source jumper to EXT.
How do I connect an Arduino Motor Shield?
Plug the shield into the Arduino and connect a stepper motor to motor port 2 – unlike DC motors, the wire order does ‘matter’. Connect to the top two terminal ports (coil #1) and the bottom two terminal ports (coil #2). If you have a bipolar motor, do not connect to the middle pin (GND).
Why do we use motor driver with Arduino?
One of the easiest and inexpensive way to control DC motors is to interface L298N Motor Driver with Arduino. It can control both speed and spinning direction of two DC motors. And as a bonus, it can even control a bipolar stepper motor like NEMA 17.
How do you power a motor shield?
Say a wall adapter or a single battery pack with 6-12VDC output, simply plug it into the DC jack on the Arduino or the 2-pin power terminal block on the shield. Place the power jumper on the motor shield.
Can an Arduino power a motor?
To power the motor, you need to send 5V through it and then on to ground. To give your Arduino control of the motor’s power, and therefore its rotation, you place a transistor just after the motor. The transistor is an electrically operated switch that can be activated by your Arduino’s digital pins.
What pins does Arduino Motor Shield use?
The shield uses the SDA and SCL i2c pins to control DC and stepper motors. On the Arduino UNO these are also known as A4 and A5. On the Mega these are also known as Digital 20 and 21. On the Leonardo these are also known as digital 2 and 3.
What applications do motors use?
The applications of electrical motor include the following. The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.
What is motor driver?
What is a Motor Driver? Motor drivers acts as an interface between the motors and the control circuits. So the function of motor drivers is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor.
