Hi everyone !
I try to read and write on RFID card with an arduino nano and a RFID reader the CR038 in Mifare Protocol.
I use tutorial and information from this website :
https://tutorial.cytron.io/2013/11/06/interface-mifare-readerwriter-arduino/
I can set on and off leds on my module, I can get serial number of my module but I can't read any RFID tag ....
My code block when I wait a answer from the CR038 when I ask a reading...
Do you have any idea to help me ?
Du you already work with the CR038 or another RFID mifare serial reader ?
Thanks !
