I got this rfid reader today and it dosnt seem to work.. as i understand, if i connect it's tx to arduinos rx, it should give me an STX value of 02h. Or something like that..
So.. How is this supposed to work exactly..
My code is:
As i understand.. i should get a value.
The rx light is also not blinking..
Help!
Have connected everything besides the pin 2 and pin 3..
As required in the datasheet.. have connected an led which is glowing very slightly. And an Antenna.. I do have RFID tags which are supposedly 125 khz but cnt confirm. BUT, It is supposed to return an value to the rx?
Right?
I get an output of ÿÿÿÿÿÿ

Code: Select all
int incomingByte = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
incomingByte = Serial.read();
Serial.println(incomingByte,BYTE);
}
