This is my first post here, and english is not my native tongue; so I'll try to keep it short and concise. :)
I spend some of my spare time working on cosplay/semi-professional costumes, and develop applications for a living - so I do have a rough understanding of electronics, but I'm still pretty much a rookie when it comes to the basics.
Currently I'm working on a costume which will have various LEDs embedded into it, like color-changing ones in the eyes, and additional ones for certain markings. Installing and controlling those with an Arduino is all peachy - but I'd like to go a step further, and allow the wearer to control/interact with the program.
What I'd like to do is use the gloves of the costume and have a way to detect if (and which) of the 4 fingers is pressed against the palm (or thumb would work too!), so that I can respond to this programatically.
Attaching conductive plates to the fingertips and to the thumb/palm would be the easiest way... but that'd be fairly ugly, so I'm looking for a smarter way to do it.
If I were to pull 5 wires to the glove, have one go to the thumb/palm, one to each fingertip, are there any components I could use to figure out which one (or, and that'd be the most awesome case - which ONES) close(s) the "circuit"? Components should be as small & flat as possible, and must work despite being hidden under the cloth/material of the glove - which could be up to 2-3mm of fabric.
If you need further info, let me know; and thank you in advance for any replies and nudges in the right direction.
