Stepper motor controlled with computer parallel port LPT
The program was written in TurboC and I probably did not saved the file but the program is al visible in the video if you want to copy but I do not believe anyone still uses the old TurboC 
With this driver motor uses about 2.5W a lot more is waisted on the power resistor so is not very efficient but is simple to build.
