I have a mfrc522 rfid reader and a aurduino uno. I need to turn on a light when a card is above the sensor and turn off it as soon as the card is removed. How can i doo that?
Depends on what program you have chosen to read the mfrc5cc. There are many already written. Which one did you choose to use? Or did you create one from scratch? If so Please share it :)

My thoughts exactly. The more m's. the less I feel inclined to even read the question.
Thanks for your support on this matter, ChrisTenone. That is exactly how I felt.
