AJB2K3 Posted June 26, 2004 Report Share Posted June 26, 2004 this is gunna sound stupid but - have yo tryed the manufactors? one time they had docs and progs free for that sort of thing?this is how i under stand.a PIC has two prong to read the Ibutton (a modified button cell battry connector) a PTM button connected to the pic to "programe" numbers and a relay to activate the lock(standered alarm system = 12 or 24 V).the PIC is programed to read the ibutton chectk the number with an internal list of numbers if the numbers match the relay is activated removing power from the lock allowing the door to open.to program the list the PIC is programed so a Ibutton is put in contact, the button is pressed and the pic rembers the code. This is the professional way of doing it but iff you want a better discription reply. Quote Link to comment Share on other sites More sharing options...
