I apologize for the time between posts, but the solution to this problem, the images by the OP are not loading - so the problem for anyone new encountering it (like myself) is still just that - a problem.
The OP figured out why pins 9 and 10 were asking for redefinition (on an Arduino Uno 3 w/RC522 Module at 3.3v, the setup using power drawn from a USB 2.0 cable connected to a laptop computer, using the libraries as posted from GitHub.com and using the most recent Arduino IDE available currently) - can anyone explain what is happening here causing the board to continually register this problem and how one might fix it (w/o an "expert" on an open forum soliciting money for writing code preferably...)? I've googled this numerous times - the problem has persisted since 2014...never a clear answer except potentially by the OP in this topic...but w/o the images, I still fail to understand...
The output I receive is exactly the same, and it's a brick wall that really makes no sense.
I'm half tempted to ditch the Uno R3 and use an esp8266 board since there seems to be no pinning v coding problems...perhaps even a Pi 3+...? But, ~4 yrs. of reading back about this problem up to this post, if the OP isn't reading, perhaps someone else can explain this recurring issue..(?)
Any help would be appreciated.
