What does a motor driver module do?
In this module, the rotation directions of motors are controlled by Motor Control Pin. The IN1 and IN2 are controlling Motor 1 while IN3 and IN4 are controlling Motor 2. Beside motor rotate direction, this Motor Driver Module is able to control motors’ speed as well by Motor PWM Control Pin.
What is L298 motor driver?
The L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors.
What is 5V en jumper?
5V pin supplies power for the switching logic circuitry inside L298N IC. If the 5V-EN jumper is in place, this pin acts as an output and can be used to power up your Arduino. If the 5V-EN jumper is removed, you need to connect it to the 5V pin on Arduino. ENA pins are used to control speed of Motor A.
How can I make motor driver at home?
Build Your Own Motor Driver
- Step 1: Gather the Parts. An Arduino. A breadboard.
- Step 2: Wiring. Hookup all the components according to the circuit diagram shown above.
- Step 3: The Code. Upload the following code to arduino.
- Step 4: Done. Now Power the arduino and see your motor spinning with varying speeds.

Why do I need a motor driver?
Motor drivers acts as an interface between the motors and the control circuits. Motor require high amount of current whereas the controller circuit works on low current signals. 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.
What is the difference between L293D and L298?
L293 is a quadruple motor driver that uses a half-H driver while L298 is a dual full-H driver, i.e, in L293 all four input-output lines are independent while in L298, a half-H driver cannot be used independently, only a full H driver has to be used.
How many motors can L298 control?
L298N Module can control up to 4 DC motors, or 2 DC motors with directional and speed control.
Why is motor driver used?
Which motor is used in toys?
Reluctance motor.
How do you control motor speed?
Thus, the speed of a DC motor can be controlled in three ways:
- By varying the supply voltage.
- By varying the flux, and by varying the current through the field winding.
- By varying the armature voltage, and by varying the armature resistance.
What is the difference between a motor controller and a motor driver?
Motor Driver VS Motor Controller The main difference between a motor controller and a motor driver is, the motor controller is responsible for the controlling speed, torque, the direction of the motor whereas a motor driver is responsible to provide enough electrical power to the motor as per requirement.
How many types of motor drivers are there?
Types of drives There are three general categories of electric drives: DC motor drives, eddy current drives and AC motor drives.
Can I use L293D instead of L298?
No. Drive voltage or the external voltage required to run the DC motor can be anywhere between 4.5V to 36V for L293D whereas between 5V to 46V for L298N. The maximum output current through one channel of L293D is 600mA whereas L298N Motor Driver can give up to 2A from both channels.
What is the difference between L298 and L298N?
The L298N H-Bridge One of the most popular is the L298N. The L298N is a member of a family of IC’s that all have the designation “L298”. The difference between the family members is in the amount of current they can handle. The L298N can handle up to 3 amperes at 35 Volts DC, which is suitable for most hobby motors.
Can we connect 4 motors to L298N?
Connect the Arduino Digital Pins to the L298n Module see our example diagram below, in the diagram we have 4 and 2 DC motors so digital pins D9 D8, D7 and D6 will be connected to IN1, IN2, IN3, and IN4. Then connect Digital 10 to module pin PWM 1 you need to remove the jumper fist plug Digital 5 to module PWM 2.
Do you need a motor driver?
So mainly, any motor usually needs a driver circuit because its voltage/current requirements are different from the device that’s trying to control it. Show activity on this post. At a high level, a motor driver takes a “logic-level” input (desired “effort”) and delivers a corresponding “high-side” output to the motor.
