Electronics • View topic - RE: New Comer, Ardumoto + Stepper Tutorials
I cannot seem to find any good or understanding Ardumoto tutorials online... for stepper motors.... however tons of people seem to be using them just fine without a hitch!! I bought a Arduino Uno (SparkFun Kit) and also the Ardumoto, and a Motor (ROB-10846) all from SparkFun. well technically Creatron Inc, however they supply Spark Fun Kit. great kit you guys have!!!

Servomotori Motore passo passo 1.8° dim23 5V 260mNm RS DSH56EX8AA4100000 consegna in 24 ore
Motori passo-passo con/senza prolunghe albero posteriore Alcuni motori dispongono di configurazioni a 8 cavi che consentono la massima flessibilità di collegamento a qualsiasi scheda di azionamento motore passo-passo standard. Gli induttori possono essere collegati in serie o in parallelo per i diversi requisiti dell'azionamento Alcuni motori sono dotati di connettore da 0,1 poll. montato sul conduttore volante (vedere la seguente tabella) e tutti sono dotati di cavi Il connettore adatto raccomandato è codice 479-181
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.
You seem to be looking for Stepper motors too^^
These 48 Ncm Nema 17 motors have the price performance

You can also get weaker ones like the 26ncm one you pearled at rs components for around 12€ on ebay.
The cheapest stepper to be found on the net this model:28BYJ-48 (3.50€ incl shipping)

If you add one uln2003 transistor array for 0,30€ u can get stepper motion controll for under 4€ by flowcreation Jun 15
