30 Jul 2010 by OriginalGriff

Google! "PIC Motor Control software" gives loads of hits - refine from there for your motor requirements and you are off.It would also be a good idea to have a look at the PIC website - they have good code examples and some SD's too.

30 Jul 2010 by E.F. Nijboer

Honestly... OriginalGriff's answer has a good point. If you would want it all handed to you on a plate you should have got a kit. You could also change the schematic and use a LS7220 Digital Lock IC for example so no actual programming has to be done (except kinda programming in the 4 digit...
