L298N MOTOR DRIVER NEMA 17 HOW TO
L298N MOTOR DRIVER NEMA 17 CODE

The following video demonstrates Stepper motor control using Arduino and L298N stepper motor driver.The other benefit of using an H-bridge is that you can provide a separate power supply to the motors. When switch is open the stepper motor is rotated in clockwise direction and when closed the stepper motor is rotated in anti-clockwise direction. The switch is used to control the direction of stepper motor rotation direction. In the loop() function we use if statement to monitor the switch connected to pin 2. In these function the sequence of steps for clockwise and counter clockwise direction provided in the above table are realized using digitalWrite() function.

L298N MOTOR DRIVER NEMA 17 CODE

In the above arduino code for stepper motor control, we have created two functions cw() and ccw() that rotates the stepper motor in clockwise and counter clockwise direction. int en = 10 int in1 = 9 int in2 = 8 int in3 = 7 int in4 = 6 const int sw=2 int swstate const int t= 10 The following is the Arduino code to rotate Nema 17 clockwise and counter clockwise direction using L298N stepper driver. A high signal sent via pin 9 for example is 1 in the above table. The A, AвЂ™,B and BвЂ™ phases refers to the Arduino digital pin 9, 8, 7 and 6.

The following is shows the sequence of digital input signal that is sent by Arduino. In this example, the stepper motor is rotated clockwise and anti-clockwise direction. When the switch is open, the stepper motor rotates in clockwise direction and when closed the stepper motor rotates in counter clockwise direction.

Diodes are used to protect the motor driver from damage due to sudden back emf from the stepper motor.ДЄlso in the circuit schematic drawing, a switch is connected to the pin 2 of Arduino. The OUT3 and OUT4 of L298N are connected to second phase B of the Nema stepper motor. The OUT1 and OUT2 of L298N are connected to one phase A of the Nema stepper motor. The SENSEA and SENSEB are connected to ground. The Arduino pins 7 and 6 are connected to IN3 and IN4 pins of L298N.

The Arduino pins 9 and 8 are connected to the IN1 and IN2 pins of L298N. In the above Arduino L298N stepper motor driver schematic, the Arduino pin 10 is connected to the ENA and ENB pins of the L298N. The Arduino sends stepping sequence to the L298N for step direction control and speed control. The following pictures shows interfacing of Arduino, Nema 17 and L298N stepper motor controller, diodes and switch. L298N, Nema 17 and Arduino Interfacing Circuit Schematic Drawing

L298N MOTOR DRIVER NEMA 17 HOW TO

The Arduino Stepper Motor Tutorial illustrates with program code how to use A4988 stepper motor driver as stepper motor controllerto control Nema 17 stepper motor. Pololu A4988 (capable of driving up to 1.5A stepper motors) or DRV8825 (capable of driving up to 2A stepper motors) are better alternative to L298N as Nema 17 stepper motor driver. Note that for low torque and light load, Nema 17 can work with L298N but for higher torque and higher load other L298N is not recommended. Video demonstration is provided at the end. Arduino code for stepper motor control is provided, circuit schematic drawing of interfacing Arduino, L298N, Nema 17 stepper motor and diodes with switch is provided. To drive the Nema 17 stepper motor L298N motor driver is used as stepper motor controller. In this Arduino electronics tutorial, Arduino is used to rotate Nema 17 Stepper motor in clockwise and counter clockwise.
