This chic pet-substitute responds to touch with pulsing blue LED ‘eyes’ and a purring effect courtesy of Lilypad vibe boards. Two Lilypad Arduinos run the animal simualtion and the touch contact is implemented via conductive fabric layers –
For this, I made two layers of fabric. One with three pieces conductive fabric that goes out to the Lilypad and underneath the other that excists of one layer. In between I used an combination of fleece & cotton jersey with holes in it. The holes give the fabric the opportunity to connect by touching each other when you rub against it.
