Hello. I'm working on my final project on my campus, relating to arduino RFID mifare. I save the data in rfid in the form of a base64 row which is converted into hex form. can we read the value of that data as a string sequence displayed on the serial monitor?
You have in a variable or array, a base64 hex representation of a number and you want to convert that to a displayable form. Is that correct ?
can you show some code where it is clear what data type is representing this base64 number and some sample contents ?
