"No, an AND gate is still not the way to drive a relay. "
FYI : IT WORKS FINE !!!!

Wake up !

You don't have to have a boxcar full of proposals and specs to blow your nose.

I was told you guys were expert .. we asked humbly for help and got nothing but a bunch of negatives. If you can't help then why not just keep quiet until maybe someone who does know something can help?

STILL WAITING (PROBABLY FOR ETERNITY) FOR SOMEONE TO SAY SOMETHING LIKE (duh):
HERE IS A WEBSITE FOR SUCH AND SUCH EVAL BOARD and KIT, IT COMES COMPLETE WITH ALL HARDWARE NEEDED AND SOFTWARE TOO AS WELL AS DEBUG TOOLS . ITS GOT IT ALL YOU NEED TO DO YOUR SIMPLE PROJECT. IF YOU NEED HELP AFTER YOU GET IT PLEASE FEEL FREE TO WRITE.
We are really dissapointed at so many who profess to have knowledge but can't seem to use common sense. If you look back thru all the messages you can easily see the speces we are working with and you should have presumed room temp, non volatile environmnet (like cots, not mil spec) not ruggedized etc. You could have already had us on track to either do it ourselves or in the best case have already had it done. (I would not call myself expert if I were you). You seem to be overly obsessed with specs specs specs when you already have tons of information to get started with.
NOT TO WORRY - WE FOUND A TRUE EXPERT WHO HAS ALREADY (NOT THRU THIS SITE) STEERED US INTO A KIT WHICH WILL DO IT ALL (yes 16 input channels).
ALL WE HAVE TO DO IS WRITE THE SW AND LOAD IT IN, CONNECT OUR INPUTS AND OUTPUTS AND WE ARE OFF AND RUNNING. thanks for nothing !!
Next time we need nothing and negatives too, we will be sure to contact you. FOR SHAME !!!
