Stepper motor arduino code12/13/2023 ![]() In this function, I am continuously increasing the value of the count i.e as many times you send the command H the speed of the stepper motor will increase continuously.In Accelerate function, you have to send the command H through the serial port to increase the speed of the stepper motor.I have declared a variable named as count.I have made two different functions for increasing (accelerating) the speed of the stepper motor and for decreasing (deaccelerating) the speed of the stepper motor respectively.In this section of the tutorial Stepper Motor Speed Control using Arduino, I am going to elaborate you about the Arduino source. L298 Motor controller manipulates the Arduino's commands and starts to control the speed of the stepper motor.Arduino UNO communicates with the L298 motor controller to control the speed of the stepper motor.Block diagram is shown in the figure below.It tells us that how the information is exchanged sequentially among all the components used.Block diagram will be helpful for use for the better understanding of the exchange of information.At the end we should close the serial port so that exchange of unnecessary commands through the serial port could be avoided.If the minimum limit of the speed of the stepper motor is not reached then we have a option to reduce its further.Similarly if the minimum speed of the stepper motor is reached then the program will rotate for the next commands.If the stepper motor is not rotating with its maximum speed then we can increase its speed.Then there is a method to check the speed, if the speed is greater than the maximum speed of the stepper motor then the program will wait for the next command.First of all we need to start the serial port so that our communication could be started.Flow chart for the Stepper Motor Speed Control using Arduino is shown in the figure below.I have made a flow chart so that you can easily understand the entire algorithm because sometimes it becomes difficult to understand the algorithm with the help of the source code.rar file, extract it and enjoy the complete source code. You can download the complete Arduino source code here by clicking on the button below.If the stepper motor is rotating slowly and you enhance its speed, then the speed of the motor will increase in proportion to the number of accelerating command sent through the serial port. ![]() If the stepper motor is already running at its maximum speed and you want want to accelerate it further then nothing will happen to the speed of the stepper motor. In the tutorial Stepper Motor Direction Control using Arduino, I will explain you about making an algorithm to run the stepper motor at different speed. Stepper Motor Speed Control using Arduino Similarly the same procedure will be followed to increase the speed of the stepper motor. If the stepper motor is rotating at its maximum speed and you are continuously sending the command through the serial port to reduce its speed, it s speed will be reduced in proportion to the number of command sent through the serial port. In this tutorial I will explain you about making an Arduino program for Stepper Motor Speed Control using Arduino with the help of the serial communication. So, they will be a lot helpful for the better understanding of this tutorial. Before going into the details of this tutorial you must have go through my previous tutorials because I am using the same hardware. Now, in this tutorial I will explain you about the program which will helpful for Stepper Motor Speed Control using Arduino. If you are working on Stepper Motor, then you must have a look at Stepper Motor Direction Control using Arduino, Stepper Motor Direction Control using Matlab and Stepper Motor Direction Control using NI LabVIEW. ![]() Moreover, I have also discussed the DC Motor Speed Control using Arduino, Matlab and LabView. Today, I am going to tell you that how to make a simple algorithm for Stepper Motor Speed Control using Arduino. I have already discussed with you about DC Motor Direction Control using Arduino, Matlab and NI LabVIEW. Hello everyone! I hope you all will be absolutely fine and fun.
