Hello, im trying to make an rfid project, but i have problems with my rfid. It was working fine before, but the it suddenly stopped. Everything is connected fine, bc it was working before. My rfid msc522 isnt even lightning now. Have i broken 3.3v on my arduino uno or rfid?
remove all the wires, and re-wire it, it may be a bad connection.
Please post schematics.
The fault can be a bad contact in the breadboard but it can also be a wrong connection damaging something.
what does schematics mean?
did already a hunderd times, but the light isnt even working on rfid:(
Just try connecting 3.3 and gnd to uno check if the led works or not sometimes led may get complaint but the board still operates. if you have doubt about the point of 3.3 v then check it with multimeter if you dont have one then try lighting a led (led bulb )using 3.3 and gnd
with 3.3 and gnd led wasnt working, im going to check 3.3v
Any updates
im in school rn, gonna try this in 6 hours +-

are you sure it's a 3.3V module ?
update, led lught is working
yeah, my arduino uno has 3,3 and 5v, and rfid needs 3,3
also, arduino serial monitor says that there is miscommunication between the wires, so it still sees the arduino rfid, but its not lightining up
everything is connected fine and 3.3v is working on arduino uno( i checked it with led light ) so i think my rfid is broken
is there an answer or the rfid is just broken?
you said about getting output .So mostly its wrong wiring .can you share the output and the circuit diagram you are using
Can you post a clear picture of the module - are the pins labeled ? Is the header correctly soldered ?
It might be broken but I would first triple check and change the wires - those DuPont cables sometimes are broken inside you should be able to put all the cables next to each other in nice row
Move the module also elsewhere on the breadboard or use male to female cables to connect the module just in case the breadboard has an issue
The pins assigned in code are same? SDA(SS) and RST
im going to check everything home
