Stepper Motor--Can I run it without sriver board
Hello there.Any idea how to use a stpper motor without a driver board. I am doing a project .I want to save some time. Much detailed answer will get full marks.

it is stepper motor rs part number 440-436. I will write a programme to run this motor to run the lift system. it is a proto type project. i do not want o go into the hassel of buying and spending on driver board.
You don't need a driver board, but you will need some sort of interface chip to handle the inductive load.
Here is a sample design with driver chips.

you may be able to make an analog to digital board to attach to your pc printer port and a quick basic program to drive it. basically you are not going to get to far w/o a driver board.... I use to design microprocessor based circuits and make my own PCBs... so i am wondering " why? " you are asking this question... maybe that will help us answer your question better.

please read above that y I am asking this. Also I am thinking to use darligton array chip to drive the motor from micro controller cuurent. I do not how good is this idea. I am a beginner and not good at projects.
The ULN2003 that is used in the sample design in the link I gave above has seven darlington drivers with protection diodes. These chips are designed to work with stepper motors. You can drive them with uC outputs.

What uC are you planning to use? You can usually find reference designs on line.

I am planning to use ATmega128 and I am using avr visual studio to right the c code.

There are lots of sample circuits and code here:

All you would need is the uC and a ULN2003 driver.
You can get them from DigiKey for less than $1.

I think I will need diodes as well. I am not sure wether I need capcitors or not do you?
