I'm currently working on a University project which will use an Arduino Lilypad to communicate a message onto Twitter using a duplicate of the same device. However, I am unsure what parts I will need apart from the Lilypad to make this work. Below are a few questions I have initially.
Can I use Lilypads along with the XBee?
How could I communicate a message between the two devices? (my thoughts are to maybe use RFID technology, but I assume this will not enable me to send a custom message, e.g. Twitter username).
Is there a way to store information on a device which can attach to Arduino easily?
The main factor of this project is that it is portable. Power is not an issue as this will only be a concept and so will plug into a computer for a demonstration.
If anyone has any ideas I would be very grateful.
