However, the speed of a motor is determined by the how frequently these coils are energized. With the following sketch you can control both the speed, direction, and the number of steps/revolutions. After each example, I break down and explain how the code works, so you should have no problems modifying it to suit your needs. For the complete step by step explanation, you can watch the video given at the end of this Article. Please excuse me for asking stupid questions The best way to do this is to check the datasheet of the motor. For this, we use the function setSpeed(). Chopper drive is a method of providing a constant current source to a device. The name ‘myStepper’ will be used to set the speed and number of steps for this particular motor. After some hunting around we found a neat motor control module based on the L298N H-bridge IC that can allows you to control the speed and direction of two… Cool project! The compiler will replace any references to this constant with the defined value when the program is compiled. Instead, it is recommended to use a dedicated stepper motor driver like A4988. Stepper Motors can be categorized between Servo Motors and DC Motors as you can control the angular position of the shaft as well as rotate the shaft freely in either direction. And as a bonus, it can even control a bipolar stepper motor like NEMA 17. You can upload the following example code to your Arduino using the Arduino IDE. If you want to change the direction of the motor, you can set a negative speed: stepper.setSpeed(-400); turns the motor the other way. In setup section of code, we set the speed of stepper motor by calling setSpeed() function and initialize the serial communication. (No acceleration or deceleration is used). You can install the library by going to Sketch > Include Library > Add .ZIP Library… in the Arduino IDE. If you would like to learn more about other stepper motor drivers, then the articles below might be useful: The Arduino Motor Shield Rev3 also uses a L298 driver. Outputs of the Bridge A; the current that flows through the load connected between these two pins is monitored at pin 1. When you remove the jumper, you need to provide the board with 5 V from the Arduino. In this case, the stepper motor turns 2 revolutions clockwise with 200 steps/sec, then turns 1 revolution counterclockwise at 600 steps/sec, and lastly turns 3 revolutions clockwise at 400 steps/sec. This means that the current draw depends on the relationship between the inductance and resistance (L/R) of the stepper motor that you connect to it. Grove Starter Kit For Arduino --- Stepper Motor & Driver. The connections are fairly simple. Next, we simply use the function runToPosition() to let the motor run to the target position with the set speed and acceleration. With the following sketch you can add acceleration and deceleration to the movements of the stepper motor without any complicated coding. Outputs of the Bridge B; the current that flows through the load connected between these two pins is monitored at pin 15. In this case it’s 200 i.e. In the loop I make use of a while loop in combination with the currentPosition() function. The L298N Dual H Bridge DC/Stepper Motor Driver Controller Module is for driving two robot motors. Speeds of more than 1000 steps per second can be unreliable, so I set this as the maximum. Finally, connect the A+, A-, B+ and B- wires from the stepper motor to the module as shown in the illustration below. Each steps is defined by a step angle. The L298N is a dual-channel H-Bridge motor driver capable of driving two DC motors and one stepper motor. In the first example we will look at the Stepper.h Arduino library. While this is not the case, we run the stepper motor at a constant speed as set by setSpeed(). H-bridge drivers are used to drive inductive loads that requires forward and reverse function with speed control such as DC Motors, and Stepper Motors. For this, we use the function setAcceleration(). High Current Bipolar Stepper Motor Controller project is based on chopper drive. You can create multiple instances of the AccelStepper class with different names and pins. l298p (powerso20) block diagram.. operating supply voltage up to 46 v. total dc current up to 4 a . It takes the steps per revolution of motor & Arduino pin connections as parameter. So in this case I check if the current position of the stepper motor is not equal to 200 steps (!= means: is not equal to). Chopper drive allows for use of higher voltage power supply for better performance and higher speed. Passing a negative number to this function reverses the spinning direction of the motor. Your email address will not be published. In the loop section of code, we simply call the step(steps) function which turns the motor a specific number of steps at a speed determined by the setSpeed(rpm) function. Filed Under: Arduino, TutorialsTagged With: AccelStepper, Arduino, Driver, Stepper, Stepper Motor, Tutorial. Driving is done by software switching the IOs (bitbanging) and make use of the Arduino MKR's PWM timers. In this case I called the stepper motor ‘stepper’ but you can use other names as well, like ‘z_motor’ or ‘liftmotor’ etc. When the jumper is in place, the onboard voltage regulator is active (12V max to 5V). It can control both speed and spinning direction of of any Bipolar stepper motor like NEMA 17. A digital electric motor that moves one step at a time and each step is defined by a step angle. I set it to 100, so we should see around 1.6 revolutions per second. When I say control a DC Motor, I mean you can start a motor, stop it, make it rotate in forward direction, backward directions, increase the speed of rotation and also decrease the speed. I have included a wiring diagram and many example codes. Supply Voltage for the Power Output Stages. In this article I have shown you how you can control a stepper motor with an L298N motor driver. Since the driver can supply a maximum of 2 amperes per channel, you need to find a stepper motor that can be used in this voltage range and doesn’t exceed the maximum current rating. If you can’t find the datasheet, you can measure the resistance of one of the windings and use the following formula to get an estimation of the current draw: I = U ÷ R or Current draw (A) = Supply voltage (V) ÷ Winding resistance (Ω). If the motor you want to drive doesn’t work with the L298N motor driver, it is best to use a chopper drive instead.
