A stepper motor is a motor controlled by a series of electromagnetic coils. The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate. This design allows for very precise control of the motor: by proper pulsing, it can be turned in very accurate steps of set degree increments (for example, two-degree increments, half-degree increments, etc.). They are used in printers, disk drives, and other devices where precise positioning of the motor is necessary. There are two basic types of stepper motors, unipolar steppers and bipolar steppers. Unipolar Stepper Motors The unipolar stepper motor has five or six wires and four coils (actually two coils divided by center connections on each coil). Bipolar stepper motors The bipolar stepper motor usually has four wires coming out of it. Two-Wire Control BX-24 code: PicBasic Pro code:

How to Wire Your Stepper You have a stepper motor and you are wondering how to wire it to your driver board. If you have a four lead motor, then that is plenty easy. But what if the motor has five, six or even eight wires? What can you do with them? MendelMax 1.5 with integrated electronics by srepmub I just finished my 1.5 (lm8uu) build, and in the spirit of open source decided to list the important parts I used here. First, I designed the following two things to be able to raise my MendelMax, so that I could mount the PSU and electronics inside, on an integrated floorboard: To protect the PSU from falling debris, aluminum netting used in model building worked really well (awesome stuff btw):

devdot.wikispaces iPhone/iPod Touch Serial Port Tutorial By Collin Meyer (TheRain) 12-09-2007DISCLAIMER: Interfacing electronically to the Iphone has the potential to cause severe damage to your Iphone or cause your Iphone to become non-functional. By following this tutorial you take sole responsibility and understand the risks of what you are doing. Summary This tutorial will explain how to use the serial RX and TX lines on the Iphone as a standard UART serial port. Software on the Iphone can access the UART using the same libraries and functions as in any UNIX software. This tutorial was created to explain how to get past this issue.

Operating Two Servos with the Arduino The Arduino can control two servos with the same ease as one. All it takes is creating a second instance (copy) of the Servo object, giving it a unique name. For example, in a two-wheeled differentially-steered robot you might call one servo object servoLeft, and the other servoRight. jleblanc 12.9.06: XBees go solo and sleep on the job I go over the basics of getting an XBee to run by itself and sleep. The basics of this are coveraed at Rob's site First set up a breadboard with the FT232R Breakout board.

Arduino/Junk pile stepper motor survey - Wikiversity - FrontMotion Firefox The purpose of this page is to record the wiring of junked stepper motors to arduino motor shields. Stepper motors have 4 or more wires going into them. Not all motors with 4 or more wires are stepper motors. Typically these motors do not settle down and display a constant ohm value. Skeinforge settings unfold, You can click 'Add Profile' in the extrusion dialog, the new profile will be a copy of the old selected profile. For example, in the extrusion dialog, select ABS, then type 'ABS_UserSettings' and click 'Add Profile'. This will create a copy of the 'ABS' settings called 'ABS_UserSettings' and you can change that without affecting the old 'ABS' settings. arhimed, Thanks for the settings, I've added them to the latest version at: []

StepperUnipolar Learning Examples | Foundations | Hacking | Links This page shows two examples on how to drive a unipolar stepper motor. These motors can be found in old floppy drives and are easy to control. The one we use has 6 connectors of which one is power (VCC) and the other four are used to drive the motor sending synchronous signals. Arduino and 7 Segment LED 7 Segment LED Click here to like us on Facebook! How many TV shows and movies have you seen with some mysterious electronic device counting down to zero on one of those 7 segment LED displays?

playground - RegulatedPositiveVoltageBooster Outputs 1/4 Watt, up to +60V DC Max Accepts any input voltage (1V minimum) Uses a simple, flexible circuit Warning: If you don't follow the instructions carefully, wiring this circuit wrong can damage your Arduino. How Can I Determine My Stepper Motor Wiring Without the Stepper Motor Pinout? - National Instruments Hardware: Motion Control Problem:I have a stepper motor but do not have the pinouts for the motor. How can I determine how to wire my stepper motor without the pinouts? Solution: In general, 2-phase stepper motors can have 4, 6 or 8-wire leads (not including any optional encoder lines).

Sanguinololu, LCD and rotary encoder with switch Having seen the PanelMax LCD and Encoder for RAMPS, I wanted to get a similar setup working on Sanguinololu. the first step was to get an ATmega 1284P working and load Marlin firmware which supports this sort of setup with minimal changes. Wiring and Testing I intended to keep using the SDSL card reader (not much point in having a screen if you have to have you computer plugged in) which left very few pins unused on the microprocessor. Conveniently these are all together on the expansion header: Controlling a Stepper Motor « cyancdesign [Chris Yanc] One day I tore apart a scanner I owned. I didn't have the power cord for it, so no loss. In fact it became a gain! Time to learn about the stepper motor. I started researching, like most things I didn't get it at first. But I didn't want to tear apart the motor.
