hi all , re-posting this over here at the suggestion of the adafruit help on the other tread...here is the post to save some time...viewtopic.php?f=19&t=37058&p=183128#p182793
used this as a starting point...http://playground.arduino.cc/uploads/Le ... relays.pdf
and now i need to give it a bit of delay on releasing the relay, so it stay on just a bit longer...it only energizes for maybe 1/2 sec or less, it sometimes will trigger the right response in the zoom, but mostly it is not quite enough time(if i hold the button down, it will multiple pulse and still not enough time, but again sometimes it will trigger the zoom). need maybe a 1sec pulse time and that would prob. be enough i know a cap maybe can do this, just not sure of value and placement...i dont want to go with a 555 timer or anything else, just need to extend the time just a bit...thanks gang.
