I'm currently looking to build the following instructable as a prototype for my University project.http://www.instructables.com/id/Arduino-Lilypad-Interactive-Passion-Sensing-Scarf/
One problem I'm having is working out how to convert this (once it's built) into my own idea. I believe many of the components will be the same, but I will need to also make some drastic changes for this to work.
My own project is to create a portable communication device which is wearable on the user's clothing, hence the Lilypad. To do this, I hope to create a device which will communicate with others and upon a connection being made using the Emitters and Phototransistors (as demonstrated in the instructable), a post will be made on the user's Twitter page which contains contact details stored on either device.
This is a similar idea to a business card, but the contact details can then be transferred to a personal Twitter page for use later.
I thought of maybe expanding on the above instructable using XBees but to be honest I really have no idea how to go about doing this.
If you can help in any way I would be very grateful.
