I actually working on a rfid modul (rc522) with my arduino UNO. I want to copy a card to an other card, with the uid etc.... So they will be similar and tween!
CAN YOU HELP ME PLEASE!!!!!!!
CAN YOU HELP ME PLEASE!
Their is never a legitimate reason to do this.
arg… I’m not good in english, sry if you think it’s not cool… But in my library “MFRC522”, I have a exemple “changeuid” and “RFID-cloner” but they are not working I dont’t know why… Moroever i have this message: “The available memory low, stability problems on the subject.” How can I stop that???

Either write the code more efficiently so it uses less memory, like using the F macro PROGMEM - Arduino Reference
However it will not help you copy that UID.
but i did this...
" Serial.println(F("Try the most used default keys to print block 0 to 63 of a MIFARE PICC."));"
" Serial.print(F("PCD_Authenticate() failed: "));"
Yes and have you seen the memory usage come down? Or was it in the code already?
Yeah it was on the code!
