I have posted this on arduino.cc forums, but didn't get a reply, so i thought i'd try my luck here.
I'm new and haven't got an arduino (yet).
I'm trying to get a buzzer/vibrator (no not what you think) go off once a piece of resistive fabric is either stretched beyond a certain point, either goes slack. The idea is also that i should be able to only make it work at certain times e.g. during 15 min every hour or so.
I would also like to be able to configure these parameters: at what measured resistance/beyond what stretch or slack should the buzzer go off and what is the time interval it should work.
Is arduino (lilypad?) a good solution?
Could anyone give me a nudge in the right direction to start this project? Materials needed, input, output... any help is more than welcome!
Thanks!
Oh, i'm on Mac, don't know if that's of any importance for arduino.
It's going to be stretched between two points. If these point move relative to each other (thus being more or less stretched) the measured resistance in the fabric will change. Beyond or below a certain stretch, i'd like to have a buzzer go off. The resistance of the available fabrics come in all kind of ranges, from 100-200 Ohm to a few MOhm
In the meantime, i've been googling around some more. And i've seen i can use a reference resistor and measure the voltage going through the fabric. Do you think this is the right way to do it Thanks!
I seem to have been googling around with the wrong search terms....Arduino + Stretch sensor seems to give me lots of results!
I'll continue searching with this, if you do have tips (like the timer option i'm looking for), they still are welcome though, because i'm a total newbie with arduino.
