Maybe a stupid error but i'm not able to compile this code, it always tell me that the KeyCode was not declare in the scope.
Here the code:
// RFID reader for Arduino
// Wiring version by BARRAGAN <http://people.interaction-ivrea.it/h.barragan>
// Modified for Arudino by djmatic
// Re-Modified for Arduino and 125Khz JsxzLz RFID Kit from Ebay by Biohazard
// RFID reader comes with 11 pins: D3 D2 D1 Rest Mcst Gnd L1 L2 PC TX VCC
// We need these to be connected:
// Rest to Arduino pin 2
// Gnd to Arduino GND
// L1 and L2 to the antenna
// TX to Arduino RX0
// VCC To Arduino 5V
int val = 0;
char code[14];
String keyCode;
String master = "4B00108513470F";
// 10 digits card code
// 2 digits parity bits
int bytesread = 0;
void setup() {
Serial.begin(9600); // RFID reader TX pin, Baud rate: 9600, Data bits: 8, stop bit: 1.
pinMode(2,OUTPUT); // Set digital pin 2 as OUTPUT to connect it to the RFID RESET pin
digitalWrite(2, HIGH); // Activate the RFID reader
Serial.println("rfid ready to read");
}
void loop() {
if(Serial.available() > 0) { // if data available from reader
if((val = Serial.read()) == 10) { // check for header
bytesread = 0;
while(bytesread < 14) { // read 14 digit code
if( Serial.available() > 0) {
val = Serial.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 == 14) { // if 14 digit read is complete
keyCode = code;
keyCode = keyCode.substring(0,14);
if (KeyCode == master)
Serial.println("Master key passed");
}
bytesread = 0;
digitalWrite(2, LOW); // deactivate the RFID reader for a moment so it will not flood
delay(1500); // wait for a bit
digitalWrite(2, HIGH); // Activate the RFID reader
}
}
}
I declare the KeyCode at the statup so why this error
Thanks
