What does the Arduino Motor Shield do?
The Arduino Motor Shield allows your arduino to drive DC and stepper motors, relays and solenoids. The Arduino Motor Shield is based on the L298, which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors.
What is motor shield?
The Motor Shield is a driver module for motors that allows you to use Arduino to control the working speed and direction of the motor. Based on the Dual Full-Bridge Drive Chip L298, it is able to drive two DC motors or a step motor.
Do you 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.
How do you use the L293D motor driver shield?
The L293D motor driver shield includes two L293 motor driver ICs and a 74HC595 shift register IC.
…
To control the DC motors, use:
- Pin 11 for the motor port M1.
- Pin 3 for the motor port M2.
- Pin 5 for the motor port M3.
- Pin 6 for the motor port M4.
- Pins 4, 7, 8, and 12 may also all be used.
Why do I need a motor shield?
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.
How do I know if my motor shield is working?

Why do you need a motor shield?
How do you use a motor shield?
Arduino Tutorial: Using a Motor shield! – YouTube
What is the difference between motor shield and motor driver?
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 many motors can be connected to L293D?
two DC motors
The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction.
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.
How do you test a motor shield?
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 many motors can an Arduino control?
The Arduino Mega 2560 can control 14 stepper motors: May be but it can control a lot more than simply 14. Remember it only takes 2 outputs to control a motor so divide the number of output by two to get the maximum number without adding more outputs from a port expander.
Can the L293D run 4 motors?
L293D Motor Driver & 74HC595 Shift Register
As the shield comes with two L293D motor driver chipsets, that means it can individually drive up to four DC motors making it ideal for building four-wheel robot platforms. The shield offers total 4 H-Bridges and each H-bridge can deliver up to 0.6A to the motor.
Can I connect 4 motors to L293D?
So the answer is no, it won’t allow the independent control of four motors, but you could possibly connect two in parallel to each output, depending upon the application. If you want to use 4 DC motors with L293D, you will not be able to control their direction (polarity across motors).
How do you wire an Arduino Motor Shield?
It is recommended that you always use one. To connect your external power supply, connect the positive (red) wire from the power supply to the “Vin” terminal, and the ground (black) wire to the “GND” terminal. Finally, upload the code to control the Motor Shield to the Arduino.
How to connect motor shield?
Can we connect DC motor directly to Arduino?
By connecting an L298 bridge IC to an Arduino, you can control a DC motor. A direct current, or DC, motor is the most common type of motor. DC motors normally have just two leads, one positive and one negative. If you connect these two leads directly to a battery, the motor will rotate.
Can I connect DC motor directly to battery?
Yes you can if the battery potential is less than the emf induced by dc motor. You need to rotate the motor with some speed by any external mechanical force. The motor will then convert it into electrical force and then deliver it to battery.
Why L293D IC is used?
The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
How many motors can be controlled by L293D?
The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction.
How does L293D control speed?
Control the Speed of Two Motors
The L293D will send power to the motors depending on the voltage applied to the enable pins. The higher the voltage applied to the enable pin, the more power will be supplied to the motor, and the faster it will spin.
How do I run a 12v DC motor on Arduino?

Can a 24 volt motor run on 12 volts?
Therefore, provided you chose a controller suitable for the motor you use, you can usually run a motor 12v motor from a 24v battery with no effect except that full speed is doubled.
