What is a l298n motor driver?

The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A.

Why do we use motor driver L298N?

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.

What is an L298?

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.

How does L298N control motor speed?

Control DC motors with the L298N

  1. If you send a HIGH signal to the enable 1 pin, motor A is ready to be controlled and at the maximum speed;
  2. If you send a LOW signal to the enable 1 pin, motor A turns off;
  3. If you send a PWM signal, you can control the speed of the motor. The motor speed is proportional to the duty cycle.

How many motors can be connected to L298N?

L298N Module can control up to 4 DC motors, or 2 DC motors with directional and speed control.

Why is motor driver used?

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 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.

How does the L298N work?

The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A.

How many pins are there on the L298 motor driver?

L298 Motor Controller Pins

L 298 motor controller has fourteen (14) pins in total, each having different individual function. All of the 14 pins along with the pin number are given in the table shown below.

How do you control a motor?

Thus, the speed of a DC motor can be controlled in three ways:

  1. By varying the supply voltage.
  2. By varying the flux, and by varying the current through the field winding.
  3. By varying the armature voltage, and by varying the armature resistance.
