    This is my code .i want to do my servo to rotate 0to180 when rfid scan specific tag.and rotate 0 to 60 when scan another tag.
    But the issue is .i want to change the servo pos when rfid scan once .
    The above program runs when the rfid scan the tag after removing it didn’t work. Pls help by providing some codes.
