We started with an old pouch for a digital camera. We have used only one part of it and turned it inside out. Then we discovered it had a flap at the (former) bottom. This flap is in an upright position, it can be pushed against the bottom, but regains its former position. SO we can use it as a "button".
Step 1: Materials & Tools & Script
An old pouch of a digital camera
a cheap piezo speaker
male connectors for the PINS of the ARDUINO
link to script
Step 2: Conductive Parts
We had the idea of embroidering two images on the surfaces which touch when the button is pushed. These images were a sun and a rainin cloud. (It was just after the holidays.)
The conductive thread gives us the possibility to make images of the silvery thread which can conduct electricity, so a signal is transmitted, just like the aluminium foil.
Step 3: Adding the Sound
The wires connected to the PINS 2 and 3 are continously checked for touching.
When touched the melody is played on PIN 8, like the example in:
The speaker can be hidden in the pouch.
When pushed the ARDUINO produces the melody triggered by the button.
Step 4: What Follows
make our own "ARDUINO" which fits into the pouch.
add a transceiver to this ATmega 328,
using another ARDUINO transceiver attached to the computer to catch the signal of the former
and have a FLASH movie react on the pushing of the button...this FLASH movie could be beamed on the wall....
The pouch then becomes a object wireless connected to the laptop.
