Connect in1 of the ic to pin 8 of arduino.
Motor driver circuit arduino.
Connect 5v and ground of the ic to 5v and ground of arduino.
It can control both speed and spinning direction of any unipolar stepper motor like 28byj 48 or bipolar stepper motor like nema 17.
Warning do not drive the motor directly from arduino board pins.
L293d motor driver arduino interfacing.
This may damage the board.
What is a motor driver a motor driver is a small current amplifier whose function is to take a low current control signal and then turn it into a higher current signal that can drive a motor.
One of the easiest and inexpensive way to control stepper motors is to interface l293d motor driver ic with arduino.
Each channel on the module can deliver up to 2a to the dc motor.
In the arduino dc motor control using l298n project we will control both the functionalities of a simple dc motor i e.
