Linking multiple arduinos together with a remote wearable sw

Post by sosafontaine »

Ok, so I am very new to arduino...like newborn level new. I'm a teacher and helping my students with an art installation. But need just a tad bit of guidance.

They want to combine movable wallpaper with movement in a dress.
Their concept is: when the dress comes close, they want these wall mounted origami pieces to move.

So the idea is to use fabric or paper origami, arduino and muscle wire/flexinol to move the pieces. Since using paper or very light fabric, we think the wire should work instead of there servo approach.

1. Can you connect multiple arduinos in a parallel style circuit?
They want to have somewhere in the range of 25 origami pieces move at the same time. Or how many separate origami pieces can we connect to one arduino?

2. Any ideas for a remote switch? They want the wall origami to move when the model wearing the dress gets close. So either some sort of motion sensor, or maybe a flexswitch in the dress?

I would appreciate any input or even direction to other "ask an expert" type forums.

Really trying to help my students figure this out! Thanks!!

Lots of options for sensing proximity. What kind of range are you thinking of? The Sharp IR rangefinders are a good choice for up to a meter or so. Ultrasonic rangefinders work up to several meters.

The Arduino can't drive the muscle wire directly. You will need a simple transistor circuit to switch the necessary current.
Something like our Metro Grand Central has enough pins to control 25 of your origami pieces easily.
