I have made a simple block diagram for stepper motor direction control using arduino, which will be helpful to clearly understand the algorithm and the assembling of the components of stepper motor direction control using arduino. The following sketch can be used to run one or more stepper motors continuously at a constant speed. Arduino stepper motor control use arduino for projects. When building arduino projects with stepper motors, such as cnc machine, plotter, or animated art, there comes a moment when the steppers need to be controlled manually. Different colors were only used to make it easier to see. Have a go at that and if it does not work post your code. The stepper motors are used to precisely control movements, whether in cars, robots, 3d printers or cnc machines. Sometimes these steps are so small that the overall rotation of a stepper motor is indistinguishable from that of a conventional one. Stepper motor is a type of brushless dc motor that converts electrical pulses into distinct mechanical movements i.
This is the diagram we will be following in order to use the arduino to control our stepper drivers. A stepper motor requires a number of step pulses to get to your desired position. Since you need to drive 3 stepper motors you can either get 3 different driver units of same kind one driver unit for each motor or get some kind of 3 axis cnc shield controller that will hold all 3 driver circuits in one board and also fit easily on top of your arduino without making a mess of wire mesh.
