I want to set up three RFID reads to detect every single message of RFID tag on an arduino, the final show three single message at the same time, like 0415ADAB82[ch12289]0415AF5A82[ch12289]0415AF0D27. If it is no any message, just show blank.
#include <SoftwareSerial.h>
#define rxPin 2
#define txPin 3
#define ledPin 13
// set up a soft serial port
SoftwareSerial mySerial(rxPin, txPin);
int val = 0;
char code[10];
int bytesread = 0;
void setup() {
// define pin modes for tx, rx, led pins:
pinMode(rxPin, INPUT); // Set rxPin as INPUT to accept SOUT from RFID pin
pinMode(txPin, OUTPUT); // Set txPin as OUTPUT to connect it to the RFID /ENABLE pin
pinMode(ledPin, OUTPUT); // Let the user know whats up
// set the data rate for the serial ports
mySerial.begin(2400); // RFID reader SOUT pin connected to Serial RX pin at 2400bps
Serial.begin(9600); // Serial feedback for debugging in Wiring
// say something
Serial.println("Hello World!");
}
void loop() {
digitalWrite(txPin, LOW); // Activate the RFID reader
digitalWrite(ledPin, LOW); // Turn off debug LED
if((val = mySerial.read()) == 10) { // check for header
bytesread = 0;
while(bytesread<10) { // read 10 digit code
val = mySerial.read();
if((val == 10)||(val == 13)) { // if header or stop bytes before the 10 digit reading
break; // stop reading
}
code[bytesread] = val; // add the digit
bytesread++; // ready to read next digit
}
if(bytesread == 10) { // If 10 digit read is complete
digitalWrite(txPin, HIGH); // deactivate RFID reader
digitalWrite(ledPin, HIGH); // activate LED to show an RFID card was read
Serial.print("TAG code is: "); // possibly a good TAG
Serial.println(code); // print the TAG code
}
bytesread = 0;
delay(2000); // wait for a second to read next tag
}
}
Im using the code from here:

Huge thanks for any help!
Many thanks,
