Hi guys!
I’m currently working on a project and I’ve come to a dead end in my research on it because I’m not quite sure I’m asking the right questions to get the right answers so I’ll try my best to explain in lamest terms what I need.
Okay, so here’s the scenario that I’m seeking advice on: I want to trigger 2 separate mechanisms or mechanical reactions upon the absence of an electronic signal that is detected by way of flexible circuit board. I want the circuit board to act as a switch to trigger these 2 mechanisms. I’ve done a massive amount of research and other than understanding the basic idea of what I need to happen, I don’t quite know how to accomplish what I’ve just explained.
My questions are as follows:
What is it that I need to do to take this basic concept and orchestrate what I’ve said? How do I use the flexible circuit as a switch to trigger each of these mechanisms?How do I employ the necessary negative logic so that the reactions only occur in the absence of the electronic signal?
What technology is required to utilize Tri-state negative logic to trigger these mechanical reactions?
And finally, do the mechanisms have to be somehow linked to the switch in order to work? If so, how?
I know that this is quite a lot of questions but I really just need a little help further understanding what I’ve come up with. Any help would be greatly appreciated and highly needed!
Thank you all in advance!
 
this is an electricians forum what you need is an electronics forum

Needs something when we went onto Tri-State I was looking up maps of New York ........................I'm sorry lads but I bet you missed me these last few weeks .haven't you

You don’t say what you’re using as the interface.

I’m not playing 20 questions with you, give the full information first.

If this is a homework question then go away and do your own work!

been having trouble with the post lately,her maj was well peed off,didn,t you hear it on tv when she said that philip was unable to attend the private birthday celebrations?terrible situation and me an international film star as well(seriously)!

I tell you what Phil I was in London that Sunday of the pageant and it was freezing, wet and really not very nice.

So sticking an old lad of 90 on a boat for 6 hours was perhaps not the best move, and I loved the bit about why they never sat on those thrones, apparently it was rumoured her maj reckons they would have looked like Posh and Becks ......... not true I know but great if it was.
