As stated in the title, I am doing a school project that requires me to scan an RFID tag to produce a QR code. I am new to Arduino circuit, hence may I know if this is possible? If yes, does anyone have a guide to do this? I've seen many tutorials and videos on RFID and QR codes but in all of them they were not used together.
There is a library mentioned in the Arduino reference to produce QR codes here: GitHub - ricmoo/QRCode: QR code generation library in C, optimized for low-power devices, such as Arduino.
Might be worth a look, I've never used it myself.
Step 1: get your Arduino to read the RFID device, storing the read value(s) in a variable (and print the result to Serial monitor or so, so you can see it works).
Step 2: get your Arduino to produce a QR code based on the value of a variable.
Step 3: make it so that the input variable of step 2 is the output variable of step 1. This should be trivial by now.
Do also ask your teacher for specifics related to your RFID and QR codes. That's what s/he is for.
Some sorts of RFID card have limits on how many bytes they can store so converting those bytes to a URL to then generate an QR code will not be possible.
Other card formats like mifaire have sectors to store date so you have to know where the sectors are and what numbers control their security locks to know how to read them.
It sounds like a particular un useful application you have been asked to do. Do you know of any practice use?
As is unfortunately quite common for a school project... I always try to have my students make something that's at least somewhat useful, much more meaningful.
I suppose making a useless application stops, or at least hinders, students from just copying a design from the internet.
