Hi there, I've bought an RFID sensor module for 134.2kHz frequency on Amazon: https://www.amazon.it/dp/B07YF84VB2/ref=cm_sw_r_wa_apa_i_J0Q2ZM229F3D5DPZDCPE From the Amazon product page, i read: GND. 2.VDC. NC: no function, do not use TXD: data send. NC: no function, do not use. NC: no function…

Thank you @MrMark for your answer. The new connections are the following: Arduino || Sensor Pin GND - PIN 1 (GND) 5V - PIN 2 (VDC) RX0 - PIN 4 (TXD) But still no valid result in the serial monitor [photo5868387453918885857.jpg] [photo5868387453918885857.jpg]

Bottom right on the serial monitor, dialog box: is the number in that box 9600 or something else?

Yes, thanks, the data rate is equal to 9600 baud. I'm afraid that the problem could be in the code, I wish to see on the monitor the code of my cat RFID chip, that is at 134.2kHz frequency

Your picture shows a Mega... No need for softwareserial Connect both RX and TX-lines to reader (Serial speed can differ from Serial1 speed) void setup() { Serial.begin(9600); Serial.println("Seriale:\n"); Serial1.begin(9600); // speed for Rfid-reader @ pins 18/19 - verify correct speedsetting Ser…

Yes, thanks, the data rate is equal to 9600 baud. not the data rate. the Serial Monitor rate.

Sorry, I meant serial monitor data rate. Is it correct? But no results [screenshot.png] [screenshot.png]

it is right. as noted above, on a Mega, you have 4 hardware serial ports. you don't need software serial. you have 3 serial ports available on pins: 14 - 15, Serial3 TX - RX 16 - 17, Serial2 TX - RX 18 - 19, Serial1 TX - RX

In which way could I edit my code, avoiding the use of SoftwareSerial? Excuse me, but I'm a beginner with Arduino Thanks everyone for the help

remove the top two lines include these in void setup: Serial.begin (115200); // set serial monitor rate to 115200 here and in the serial monitor Serial3.begin(9600); // GPS Serial setup Serial2.begin(9600); …

If I recall correctly, animal RFID chips require a reader specifically designed for them. Moreover, the European coding is not the same as the North American coding. I do not see anything in your link mentioning use for animal RFID chips. Paul
