Hello,

·· Without any information on the timer, specifically model number and connections, we wouldn't be able to even guess how to interface to it.· Please provide more details on the timer.· Include it's operating voltage too please.

If it has a dry-contact relay output then yes, you can use it with the BASIC Stamp.

That said, why do you want to use an external timer when you can code one in your program? Or do you actually need the display that the timer provides?

i just think that it would be nice to know when the prop can be ready to go for another cycle. i allready know how to have a ready led light but if people are coming through then i know if its going to be ready by the time they are next to it... and yes it says it does have the dry-contact relay output... how should i write the code for it to work.

thanks

There are a number of ways you can do it.· The easiest, I think, would be to put the relay contacts in place of the button in the attached schematic.· in your. If you were using P7 as your input, you could do something like this to wait on the contact closure:

SYMBOL Trigger = PIN7

Main:
· IF Trigger = 1 THEN Main
