I Have got my ID-12 module active and putting out the RFID tags' details to Serial as

String valu = port.readStringUntil('\n');

... then I print that to serial. But I would like to use the information from the tag to determine changes in Processing environment. For example, change the background color of a box depending on which RFID tag is placed to the reader.

Does anyone know how I can do this or where I may find coding help?

Setup:

you may want to try http://processing.org/ for the programming language, there are some projects out there that use serial data to manipulate graphics and objects on screen.
