What is L298N Motor Driver
If you’re looking for an inexpensive way to control two DC motors, the L298N motor driver is a good choice. It can control the speed and direction of two DC motors, including bipolar steppers such as the NEMA 17-type. It works by using a technique called L298N PWM to control input voltage, sending on-off pulses to the motors. Compared to ICs, breakout boards can be more convenient to prototype.
The L298N motor driver has two channels, channel A and channel B. To operate the motor in channel A, connect pins Out 1 and Out 2. Then connect pins Enable A and Enable B to the motor. The Enable A pin must be high to turn the motor on. To operate the motor in the counterclockwise direction, make the Input 1 pin low. For optimal performance of this motor type, the L298N motor driver is ideally paired with a 5V power supply.
The L298N motor driver module contains two screw terminal blocks, one for a motor and one for a Ground pin. In addition, the module has a 5V pin that can either be an input or an output. The L298N PWM signal from the motor will control the speed of the motor. Engineers have designed the circuit to seamlessly operate with a range of electronic and mechanical components, including sensors, switches, and detectors.

The L298N motor driver datasheet also has circuits you can use with your Arduino Uno R3. Read it carefully, and be sure to follow all instructions thoroughly. This IC also contains two control pins. One controls the motor’s direction, and the other controls the speed.
The L298N motor driver is a double H-bridge design, with a low level of heat and interference. This device supports up to 2A of current with a power rating of 25W. This module can drive two DC motors, one 2-phase, and one four-phase stepper. It operates on the driver voltage and requires an external 5V power supply. Once installed, it is ready to use.
The L298N module is a dual H-bridge motor driver that allows you to control the speed and direction of two DC motors. The module accepts standard TTL voltage levels and is useful for projects with powered wheels. Additionally, it finds application in regulating lighting brightness. The H-bridge circuit accepts both polarity and pulse width modulation (PWM).
How L298N Motor Driver Works
The L298N motor driver is an IC that has two input power pins. The Vs pin powers the motor, while the Vss pin powers logic circuitry. A common ground connects both pins. An on-board 78M05 5V regulator also powers the L298N motor driver. Enabling or disabling the 78M05 is possible. The L298N module can be used with Arduino Uno and Raspberry Pi.
The L298N motor driver controls both the speed and direction of rotation of a dc electric motor. It does this by using a L298N PWM system, which means it can control voltage using square wave pulses. The wider the pulses, the faster the motor will rotate. However, the exact pulse width will vary depending on the type of motor you’re driving. To find the correct value, you’ll need to experiment.
To use the L298N motor driver, first, you need to know how it operates. This is achieved via the Truth Table. The Truth Table is a special mathematical table that contains inputs and outputs based on a set of Boolean functions. In this example, you need to set the input and output pins to HIGH. You must then translate the values of the TTL input and output pins to make the driver work.
How to Connect L298N with Arduino Uno
The L298N Motor Driver is a cheap way to control DC motors. This motor driver can control the speed and direction of two DC motors. You can also utilize it to control a bipolar stepper motor, like a NEMA 17 brushless motor. The motor driver uses L298N PWM to control the input voltage by sending a series of ON-OFF pulses.
The L298N module is a dual H-bridge DC motor driver. The circuit is straightforward, with just one sketch that declares the pins on the Arduino Uno that control the motors. Then it pulls all of those pins low and calls two user-defined functions. At that point, the circuit is complete! You’ve completed your first project with a DC motor driver!
The L298N motor driver board comes with two 3.5mm pitch screw terminals. It supports a variety of DC motors with five to 35V, and it can even control relays and solenoids. It also has an integrated 5-V regulator, which is useful for supplying logic circuits. You can purchase L298N driver boards from multiple sources at reasonable prices. You can also buy an optional 5 V power input.
L298N with DC Motor
The L298N with DC motor IC is a microcontroller that can be used to drive LEDs or other loads that require a higher current. It has three inputs, pins 1 and 2 that control the direction of rotation, and two inputs 3 and 4 that control the backward and forward movement of the motor. The onboard 5V regulator controls the voltage and speed of the motor. To control the motor’s speed, the IC uses a L298N PWM signal to regulate the motor’s speed.
Using the L298N with a DC motor is extremely easy and straightforward. The sketch you’ll use to control the speed and direction of a DC motor is very simple and doesn’t require any libraries. This sketch declares the corresponding Arduino Uno pins for the motors and pulls them low. Next, it calls two user-defined functions, which control the speed and direction of the motor. In this way, you can make the motor work in any direction that you need it to.

This L298N with a stepper motor driver board is an advanced circuitry controller that uses dual full-bridge drivers to control DC and stepper motors. It is also capable of controlling solenoids and inductive loads. The L298N module has two channels and a 78M05 5 V power regulator. This board features a simple design with easy programming. This motor driver board is compatible with many Arduino projects.
To connect a stepper motor to an L298N H-bridge module, first identify the wires. Below are the steps for connecting a stepper motor to an Arduino Uno. Kindly take note that the wires of a stepper motor should exhibit identical polarization on both inputs. To use the L298N with a stepper motor, you must have a Raspberry Pi running at least 5V.
This stepper motor driver has a good CR2032-type IC. The L298N motor driver can deliver up to two Amps per coil. While this isn’t ideal for a high-end project, it is fine for basic applications. It is very robust – the chip and the resistors should last for a long time. You can also power the Pi or Arduino Uno R3 with a 5V port. Ensure acquiring a 10W resistor with a minimum rating of 20 Amps.
Alternate of L298N
If you are looking for an Alternate of L298N, here are some things to know about this particular IC. The L298N motor driver is a dual-H bridge DC motor driver IC. You’ll find that it is very similar to the L293D series but is a bit more expensive. It’s also not suitable for motors with higher voltages, like a 12-volt version.
The L298N module is ideal for custom-built robots and vehicles, while the TB6612FNG is perfect for child-sized RC toys and Micro Metal Gear Motors. While you’ll still need a transistor or MOSFET circuit to drive a DC motor, you’ll likely be running two of them at once. The Alternate of L298N also comes with easy-to-follow wiring diagrams, so you can get started quickly.
Which is Better L293D or L298N
If you’re wondering which Arduino is better for your project, you’ve come to the right place. A L293D or L298N shield is one option. You can use both to drive DC motors, bipolar stepping motors, and relays. Both shields can also drive as many as six motors. Here’s a closer look at their differences and how they compare.
L293D Driver operates at 4.5V to 36V, while L298Ns can handle up to 46V. The L293D motor driver is a low-current device, while L298Ns are more suitable for high-current applications. Both devices feature a H-bridge, which lets you control a standard DC motor through a logic chip or microcontroller. In addition, both drivers support individual half-bridge controls.
