Arduino Motor Shield Tutorial - Aurora. Small Reduction Stepper Motor - 12VDC 48-Step 1/16 Gearing ID: 918 - $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits - Aurora. This is a great first stepper motor, good for small projects and experimenting with steppers. This uni-polar motor has a built in mounting plate with two mounting holes.
There are only 48 step (7.5 degree) per revolution, and inside is a 1/16 reduction gear set. What this means is that there are really 48*16 steps per revolution = 768 steps! The shaft is flattened so its easy to attach stuff to it with a set-screw. A perfect first stepper motor and works well with the Motor Shield for Arduino. The gearing has a few side effects which are important to note. To use with the Adafruit Motor Shield, connect red to ground (middle), orange and pink to one motor port (say M1) and blue and yellow to the other motor port (say M2). Wiring Connection Diagrams.

Update: I've posted a new Easy Driver 4.2 Tutorial for those who are using the new design.
A quick tutorial on how to get things up and running with the EasyDriver v3.1 Stepper Motor Driver Board. A big thank you to Brian Schmalz, the designer of this board. It's obvious why he has called it the EasyDriver. It was indeed, an "EasyDriver" to set up ;) PLEASE NOTE: some people have overlooked the extra (ground) pin on the easydriver board. WARNING Easy Driver v4.2: Please do not attempt this tutorial with new Easy Driver v4.2 board. Here is a copy of the code used in this Video: Customer Support Forums, DIY Electronics, Open Source Hardware, Arduino - Aurora. Do you still have the board the motor was connected to?
Even though you can't find the specs on the motor, I'd bet you *can* find them for the driver chip the printer used. Most used chips of some sort, rather than discrete transistors. You can also make a guess at the voltage used, even if the printer cannot be powered up to find out directly. There will be filter capacitors on the motor driver power plane, which will have a voltage rating on them a little higher than the actual voltage. Manufacturers will not generally use a part spec'd higher than absolutely necessary, because it's cheaper that way. Epson has used some of their own chips for things, but also has used chips by other manufacturers, so it is likely you will find the specs for the driver chip. Also, if you have a need for small 3-phase brushless DC motors, laser printers and toner-based digital copiers use them in the laser scanning assembly that draws the picture on the drum. Problems with stepper motor - Aurora. Blog : Hacromatic: Electronics kits and projects worldwide - Aurora.
I couldn’t find much information about how to use the Arduino motor shield (as of late 2012), so I thought I’d show how to set up the connections for both stepper motors (4, 5, 6, and 8 wires) and DC motors, along with some basic sketches to drive them. Stepper Motors Steppers can be broadly classified as 2/4-phase or 5-phase. This breakdown covers the vast majority of stepper motors you’re likely to encounter. 5-phase motors typically provide lower vibration and smaller stepping angles than 2 and 4 phase motors, but they are less common and won’t work with the Arduino motor shield, so I’m not going to talk about those here.
That leaves 2/4 phase motors. Why do I group these together? Arduino motor/stepper/servo control - How to use - Aurora. Stepper Motor Controller - Aurora. CONSTRUCTION You can build the circuit on any type of Proto board.
We have chosen our surface-mount board as it makes a neat project and you can see all the wiring at the same time. The PROGRAM If you want to modify the program you will need a programmer, a board to hold the 8 pin chip during programming and an adapter to connect between the programmer and PC board. These are covered in our article "Pick-A-PIC. " Here are the files you will need for "burning" your chip and/or modifying the program: Step.asm Step.txt Step.hex The following program is for viewing.

Unipolar stepper motors have four coils and either five, six or eight wires.
No matter how many wires, unipolar stepper motors are interfaced in the same way. Five wires will go to the controller circuit. Four wires will be excited by pulses from the control circuit and the remaining wire(common) is given to the power supply. To identify the wires, you need a resistance meter. First, identify the common lead. Eight wire motors: Find the four pair of coils. Six wire motors: Find the two wires whose resistance to two other wires reads the lowest of the measured resistances between wire pairs. Five wire motors:Measure the resistance between all pairs of wires. 42v printer stepping motor - YouTube - Aurora. Floppy Disk Motor Hack - YouTube - Aurora. CNC machine for shaping large pieces of polystyrene foam - Aurora. Summary This instructable shows how to shape polystyrene foam, using a CNC machine. Starting with a brief introduction, design software necessary for creating an STL file is discussed. This is followed by a method for creating G-code, using an STL file as input.
After this comes the introduction to GRBL, an arduino based system for using G-code to control stepper motors of a CNC mill. Stepper drivers are mentioned, after which the creation of large CNC hardware is described. Enjoy, Richard Tegelbeckers PS.

Digital Electronics: Darlington Arrays to Drive High-Current Outputs - For Dummies - Aurora. Two electronic transistors can be connected to form a Darlington transistor (sometimes called a Darlington pair), which can switch much more current than the collector-emitter circuit of a standard transistor can.
You can use darlington transistors to switch up to 500 mA from the output of a parallel-port data pin, which is enough current to drive a mechanical relay or a small electric motor. Rather than use individual darlington transistors, you can use an integrated circuit specially designed for driving high-current loads from TTL-level inputs. The most common ICs of this type are the ULN2003, which has 7 darlington drivers in a 16-pin DIP package, and the ULN2803, which has 8 drivers in an 18-pin DIP package.
You won’t find these ICs at your local RadioShack store, but if you have access to an electronics-parts store, it probably will have this useful chip in stock. If not, you can easily find it on the Internet by searching for “ULN2003” or “ULN2803.”
