Stepper motor control via serial port

I used a code from Robin2 Serial Input Basics. I would like to control two stepper motors AccelSteper. I have no idea whats wrong. When I type the command to turn the motor the motor rotates. But when calling the STOP command the motor stops and again starts turning. Is there any way I could hack the code to run just once, every time the command is typed? First, you need to post the complete program. Create a free Team What is Teams? Learn more. Asked 2 years, 6 months ago. Active 2 years, 6 months ago.

Have you checked, if the data get's correctly transmitted by echoing it back and showing it in your application? Add a comment. Active Oldest Votes. Stepper motor has wide range of applications e. In simple word, we can say that stepper motor can be used where there is a need to move at particular angle.

In this tutorial we will learn how to make a program for Stepper Motor Direction Control using Arduino by sending dfferent commands from the serial port. First of all, I am going share the list of components used for this mini project. I want to tell you a bit about the stepper motor because all the other components are discussed in detail in DC Motor Direction Control using Arduino. Basically, stepper motors are like the DC motors that rotate in discrete steps. They have multiple arranged coils and they are usually known as phases.

Motor will rotate one step at a time if we energize each phase sequence. Collectives on Stack Overflow. Learn more. Controlling a stepper motor using Arduino and serial Ask Question.
