Includes our driver board, CAT# ME-16 and a 5-wire stepper motor that plugs directly into the board. Ideal for beginning robotics projects. Motor is a 4-phase, unipolar stepper, #28BYJ-48. User Guide for 3 axis TB6560 driver board Product Features: ⢠Toshiba TB6560AHQ chip - High power, maximum 3.5A drive current chipset! ⢠Four control inputs (divided into pairs of knives) - Allows setting of limit and emergency stop! (For example, if you want to drive 3 * 3A Nema 23 stepper motors, theoretically 24V 11A DC power. L298N H-bridge Motor Controller, DROK L298N Motor Driver Board DC Dual H Bridge Robot Stepper Motor Regulator and Drives Module for Arduino Smart Car. This stepper motor driver board uses four of the Arduinoâs pins. The box labeled âRelaysâ is explained in more detail on the Using Relays to Control Multiple Solar Machines page. For now though, just skip it and connect the wire straight into the stepper motorâs power supply. Wiring the stepper motors to the driver board can.

To control one or two DC motors is quite easy with the L298N H-bridge module. https://kijpuov.weebly.com/blog/toshiba-satellite-c55-a5302-network-controller-driver. First connect each motor to the A and B connections on the L298N module.
If youâre using two motors for a robot (etc) ensure that the polarity of the motors is the same on both inputs. Otherwise you may need to swap them over when you set both motors to forward and one goes backwards!
Next, connect your power supply â the positive to pin 4 on the module and negative/GND to pin 5. If you supply is up to 12V you can leave in the 12V jumper (point 3 in the image above) and 5V will be available from pin 6 on the module.
This can be fed to your Arduinoâs 5V pin to power it from the motorsâ power supply. Donât forget to connect Arduino GND to pin 5 on the module as well to complete the circuit. Now you will need six digital output pins on your Arduino, two of which need to be PWM (pulse-width modulation) pins.
PWM pins are denoted by the tilde (â~â) next to the pin number, for example in the image of the Arduino Uno's digital pins.

In our example we have two DC motors, so digital pins D9, D8, D7 and D6 will be connected to pins IN1, IN2, IN3 and IN4 respectively. Then connect D10 to module pin 7 (remove the jumper first) and D5 to module pin 12 (again, remove the jumper).
The motor direction is controlled by sending a HIGH or LOW signal to the drive for each motor (or channel). For example for motor one, a HIGH to IN1 and a LOW to IN2 will cause it to turn in one direction, and a LOW and HIGH will cause it to turn in the other direction.

However the motors will not turn until a HIGH is set to the enable pin (7 for motor one, 12 for motor two). And they can be turned off with a LOW to the same pin(s). However if you need to control the speed of the motors, the PWM signal from the digital pin connected to the enable pin can take care of it.
This is what weâve done with the DC motor demonstration sketch. Two DC motors and an Arduino Uno are connected as described above, along with an external power supply. Then enter and upload the following sketch:
So whatâs happening in that sketch? In the function demoOne() we turn the motors on and run them at a PWM value of 200. This is not a speed value, instead power is applied for 200/255 of an amount of time at once.
Stepper Motor Drive ControllerThen after a moment the motors operate in the reverse direction (see how we changed the HIGHs and LOWs in thedigitalWrite() functions?). To get an idea of the range of speed possible of your hardware, we run through the entire PWM range in the function demoTwo() which turns the motors on and them runs through PWM values zero to 255 and back to zero with the two for loops.

Finally this is demonstrated in the video on this page â using our well-worn tank chassis with two DC motors.
