I apologize.This is my first personal project. I have not in the least considered this forum as a "take-away" where you can find the solution without any effort.I'm trying, trying, reading, making mistakes, to understand more and learn how to use this type of technology.Of course I will do my best to learn and be able to help those in need, as you are doing with me. Thank you all.
So it is impossible to make an RFID reader of this frequency with these simple components (https://amz.run/4KHh), considering that the reader cannot power the chip. Am I right?I based my research on the functioning, and recognition, of 125kHz RFID tags used outside of Europe, studying the type of device used (a sensor that works on that frequency) and a code that would allow the Arduino unit to communicate. with the sensor, reading and printing the read values.Unfortunately, as far as the 134.2kHz frequency is concerned, literature is scarce and fragmented. For this reason I took the liberty of asking for help. Thanks for your feedback.
