It is similar to the LS in its voltage range 2. This makes it ideal for projects where the motors will be run from a 9V battery. The board can be powered using the provided screw terminals or through micro-USB, checkout out micro-USB to DC Jack adapter if you would like to use a standard power adapter with the board. The control inputs are pulled low internally, effectively disabling the motor driver outputs by default. See the truth tables in the DRV datasheet for more information on how the inputs affect the driver outputs.
Stepper motors, due to their unique design, can be controlled to a high degree of accuracy without any feedback mechanisms. The shaft of a stepper, mounted with a series of magnets, is controlled by a series of electromagnetic coils that are charged positively and negatively in a specific sequence, precisely moving it forward or backward in small "steps". There are two types of steppers, Unipolars and Bipolars, and it is very important to know which type you are working with. For each of the motors, there is a different circuit. The example code will control both kinds of motors. See the unipolar and bipolar motor schematics for information on how to wire up your motor. In this example the motor will step one step at a time, very slowly. You can use this to test that stepper motor hook up got the four wires of your stepper wired to the correct pins.
As the name implies, the stepper motor or simply step motor is a brushless, synchronous DC motor, moves in discrete steps to complete its rotation. In general case, each step in a stepper motor moves 1. The stepper motors are also available with step angles 30, The stepper motor is operated based on the principle of electromagnetism and can be controlled with or without feedback. Since its possible to control the positioning and speed of the motor precisely with the help of sophisticated computer controlled systems, the stepper motors are preferred in many precision motion control applications such as robotics. As in the case of any other motors, a stepper motor has a rotating part which is aptly called a rotor and a static part termed stator.

Whether we care to admit it or not, motors can be found all over in our everyday lives; they just tend to be hidden. Motors are present in cars, printers, computers, washing machines, electric razors, and much more. However, there are a number of people which until recently included myself that would be uncertain of how to make a motor run if they were handed one. So, let's learn something today. Let's learn how to use a stepper motor! In order to demonstrate how to use the stepper motor a hybrid stepper motor , there are a few things that I will end up using. Stepper motors are part of a class of motors known as brushless motors; these motors have a shaft but it does not physically touch anything in order to rotate. Rather, stepper motors work by utilizing electromagnets that are concentrically located around the shaft. The idea behind electromagnets is that when a voltage of any kind is applied to a coil surrounding the piece of "soft" metal, that metal becomes magnetized until the current stops flowing through the coil.
Hi to all. In this tutorial i will help you to connect an unipolar stepper motor to your arduino. In this step you need to connect the wires from stepper to the driver. Most steppers have 6 wires,three for one coil,and three for second coil,if you are not sure witch wire it's in the middle of the coil find it with Ohm meter. When you find both wires connect them together and that will be the positive terminal. Because stepper consumes quite a lot of current,you need to connect this driver to the external power supply and NOT on the arduino!! You're doing great! Now you just need 4 wires and with them connect driver shield to arudino,on arudino i selected ports 8,9,10,11,but you can use other ports too! Now the hardware is finished and we can start programing.
There are a wide variety of stepper types, some of which require very specialized drivers. For our purposes, we will focus on stepper motors that can be driven with commonly available drivers. These are: Permanent Magnet or Hybrid steppers, either 2-phase bipolar, or 4-phase unipolar. This style is common in smaller unipolar motors. All of the common coil wires are tied together internally and brought out as a 5th wire. This motor can only be driven as a unipolar motor.
