Keyestudio KS077/078 How to LED after reading NFC card

I've have this working: https://wiki.keyestudio.com/KS0077(78,79%EF%BC%89Super_Learning_Kit_for_Arduino#Project_32:_RC522_RFID_Module

Now I want an extra step so that after reading a LED is blinking. How do I approach this?

Welcome to the forum

Please post the code here, using code tags when you do

In my experience the easiest way to tidy up the code and add the code tags is as follows

Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.
