Triggering Processing Sketch with Arduino

ProcessTrisProcessTris
edited December 2017 in Arduino

I am currentlly working on a project, where a picture is being slowly revealed. I am using an rfid reader and tags, arduino and processing. The Arduino reads the tags through the rfid reader, and couples the ID of those tags to a certain value (e.g. tag ID 2A, 34, 4C, 29 is equal to value 1) The arduino code is fully functional, the problems lays in the processing code. When processing recieves a value (in this case either 1,2 or 3) it should trigger the action of the painting being slowly revealed.

Arduino Code

#include <MFRC522.h> // Include of the RC522 Library
#include <SPI.h> // Used for communication via SPI with the Module

#define SDAPIN 10 // RFID Module SDA Pin is connected to the UNO 10 Pin
#define RESETPIN 8 // RFID Module RST Pin is connected to the UNO 8 Pin



byte FoundTag; // Variable used to check if Tag was found
byte ReadTag; // Variable used to store anti-collision value to read Tag information
byte TagData[MAX_LEN]; // Variable used to store Full Tag Data
byte TagSerialNumber[5]; // Variable used to store only Tag Serial Number
byte GoodTagSerialNumber[5] = {0x95, 0xEB, 0x17, 0x53}; // The Tag Serial number we are looking for
byte GreenTagSerialNumber[5] = {0x3A, 0xB2, 0x9A, 0x29}; // The Tag Serial number we are looking for, 16, EF, 8D, C9, Card: 3A, B2, 9A, 29,
byte RedTagSerialNumber[5] = {0x2C, 0xE8, 0xAC, 0x79}; // The Tag Serial number we are looking for, 2C, E8, AC, 79,
byte YellowTagSerialNumber[5] = {0x1, 0x4C, 0x8E, 0xC9}; // The Tag Serial number we are looking for, 1, 4C, 8E, C9, 


MFRC522 nfc(SDAPIN, RESETPIN); // Init of the library using the UNO pins declared above

  // Start to find an RFID Module

    // Get anti-collision value to properly read information from the Tag
