The active PWM pin decides the motor direction of rotation (one at a time, the other output is logic 0). Pins 9 and 10 are PWM signal outputs, at any time there is only 1 active PWM, this allows us to control the direction as well as the speed by varying the duty cycle of the PWM signal.
Using l298n motor driver with a dc motor and stepper motor how to#
In the previous Arduino electronics tutorial How to use. For motor driver application it can drive two DC motors simultaneously or a single stepper motor. It is used to drive equipment which contains inductors such as solenoids, relay and motors. Pins IN1 and IN2 are the control pins where: IN1Īs shown in the circuit diagram we need only 3 Arduino terminal pins, pin 8 is for the push button which toggles the motor direction of rotation. L298N IC contains two full H-bridge drivers that can output and withstand high voltage and current. In summary: To control the direction the DC motor is spinning you use the input 1 and input 2 pins Apply LOW to input 1 and HIGH to input 2 to spin the motor forward. It is a high voltage and high current full dual bridge driver designed to accept standard TTL logic level and drive inductive loads such as relays, solenoids and DC stepper motor. In this tutorial we’ve shown you how to control the direction and speed of a DC motor using an ESP32 and the L298N motor driver.
The l298 is an integrated monolithic circuit in a 15 lead multi-watt and power S020 package. The L293D driver has 2 VCCs: VCC1 is +5V and VCC2 is +12V (same as motor nominal voltage). The L298 Dubai H Bridge is base on l298 Chip manufacture by ST Semiconductor. L298N Module is used to Control DC motor as well as Stepper Motor.
If the button is pressed the motor will change its direction directly. L298N Module is motor driver Module with dual H-Bridge. L298N Module can control up to 4 DC motors, or 2 DC motors with directional and speed control. This module consists of an L298 motor driver IC and a 78M05 5V regulator.
The speed of the DC motor (both directions) is controlled with the 10k potentiometer which is connected to analog channel 0 (A0) and the direction of rotation is controlled with the push button which is connected to pin 8 of the Arduino UNO board. This L298N Motor Driver Module is a high power motor driver module for driving DC and Stepper Motors.
