Multiple RC522's Weird Behaviour
} } ``` I only get an output from the one connected to pins 10 and 9. Why is that? The array order cannot be the problem, since I swapped the two in the code and only the one connected to pins 10 and 9 works. I also tried using 2 variables instead of an array but that didn't help. I'm using the MFRC522 library but I also tried the v2. None work correctly. I would greatly appreciate any help, Thanks, Michael

Measure how much time an NFC tag stays on RC522
I'm trying to measure of much time does a specific NFC tag stays on the RC522 reader through an ESP32. I'm using MFRC522.h library to use the RFID module, but I don't know what some functions do as it's not very well documented...

How to use that RFID reader without any library? (esp32) I only wanna check if a tag is in range, I don't care that much to UID and that stuff...
Oh man tricky subject to learn if you are a begginer. If you didn't try this library, you should check if it will work for you https://github.com/miguelbalboa/rfid. This guy made it so easy to learn from his code. It would help if you tell us witch board you are useing and what code did you write. But to sum up your dilema. You can't use IRQ pin for the thing you want, that first. Second if you want to write your code to just blink an LED when a card is near, the chip(the rfid chip info from the datasheet) needs to do this: 1. Do a slef-test 2. enabel the correct registers for it to just turn on 3. make the led blink when something is near. The self-test is maybe not needed but it worked for me so i included it in my code. In his library, MFRC522.cpp, you have on line 198 PCD_Init() function there he writes to some registers to enable them

Can a RF TRANSMITTER 433MHZ interfere with RFID MODULE RC522
/* * -------------------------------------------------------------------------------------------------------------------- * Example sketch/program showing how to read data from a PICC to serial. * -------------------------------------------------------------------------------------------------------------------- * This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid * * Example sketch/program showing how to read data from a PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID * Reader on the Arduino SPI interface. * * When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Arduino IDE * then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages * when removing the PICC from reading distance too early. * * If your reader supports it, this sketch/program will read all the PICCs presented (that is: multiple tag reading). * So if you stack two or more PICCs on top of each other and present them to the reader, it will first output all * details of the first and then the next PICC.

Flipper Zero – Portable Multi-Tool Device for Geeks
Well sure, but if you just need one feature (eg. infrared "tv-b-gone"), and you already have an arduino at home, you just need an infrared led.

If you want to open garage doors, you just need a cc1101 and an esp8266

If you want to clone rfid cards, you need one of the cheap readers, an empty card an an arduino

Yes, it's ugly, but it's cheap.
