Control Stepper Motor with L298N Motor Driver & Arduino
If you are planning on assembling your new robot, you will eventually want to learn how to control stepper motors. The easiest and inexpensive way to control stepper motors is to use the L298N motor driver. It can control both the speed and the spinning direction of any small to medium sized bipolar stepper motor such as the NEMA 17.
If you wish to control multiple stepper motors, it is recommended that you use a self-contained dedicated stepper motor driver such as the A4988. If you want to know more about it, check this tutorial out.
Controlling a Stepper Motor With an H-Bridge
The L298N module has two H-Bridges. Each H-bridge drives one of the electromagnetic coils of a stepper motor.
By energizing these electromagnetic coils in a specific sequence, the shaft of the stepper can be moved forward or backward precisely in small steps.
However, the speed of the motor is determined by how frequently these coils are energized.
L298N Motor Driver Chip
At the center of the module is a big, black chip with a chunky heat sink – the L298N, from ST Semiconductor.
Inside the L298N chip, you’ll find two standard H-bridges capable of driving a pair of DC motors or a single stepper motor.
The L298N motor driver has a supply range of 5V to 35V and is capable of supplying 2A continuous current per coil, so it works very well with most of our stepper motors.
