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?
