5 wires unipolar stepper motor + L298?

-

hi, i'm totally new controlling stepper motors (i know how dcs), , have problem :

i have unipolar stepper motor : http://www.seeedstudio.com/depot/high-quality-stepper-motor-12v-p-335.html?cpath=39_40
and driver : http://www.seeedstudio.com/depot/datasheet/l298%20dual%20h-bridge%20motor%20driver%20datasheet.pdf

and don't know how wire , control arduino, after seeing many things on internet, connected 4 wires "stepping motor" pins on of driver , :
ea 1 arduino pin , eb 1 other (but that's 2, , people did 2 on others drivers , others 4.... confused , don't know right way wire it),
vms connected 12v external source, gnd arduino grnd , +5v arduino's +5v...

my code 1 mentioned on page : http://arduino.cc/en/tutorial/motorknob without potentiometer thing, nothing working , since i'm not sure connections...

if give me tips, tell me how or point stuff did wrong, appreciate.

thanks :)

normally 5-wire unipolar drive only, since 2 windings joined together.

with little care can drive such motor bipolar, have ensure common
wire isn't carrying current between windings - can either drive both windings simultaneously
at times (so common wire @ v/2), or turn off 1 winding (all 4 switches off)
rather other "off" setting - way off winding floating.

you'll still transient currents between windings may cause issue - general
rule 5-wire motors unipolar (4-wire motors bipolar , 6- , 8-wire motors are
either).

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

How to format a Get Request

i have external server running mysql. have installed php script that, when accessed http deliver data 1 of tables. works fine browser: code: [select] http://www.seti.net/php/getevents.php i cannot figure out how send command arduino. have ethernetclient library working , can access google in example. when send command through client: code: [select] client.println("//get /php/getevents.php http/1.0"); the server returns: code: [select] </head><body> <h1>method not implemented</h1> <p>get /php/getevents.php not supported.<br /> what correct way format in arduino? i use send temperature web server. note lack of http version , additional blank line after - not sure whether difference important works: code: [select] void  sendtemptoserver() { char getrequest[80]; if (client.connect(server, 80))   {   sprintf(getrequest,"get /cgi-bin/arduino.cgi?reading=%s&arduino_id=23&sensor_id=1",t...

avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
