+ * possible, something turns off the CPU (including PWM outputs) if a
+ * Proto-Thread is taking too long. We need to find out how to sleep in

+ * Example sketch/program showing how to read new NUID from a PICC to serial.
+ * ------------------------------------------------------------------------------------------------------------$
+ * This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalb$
+ *
+ * Example sketch/program showing how to the read data from a PICC (that is: a RFID Tag or Card) using a MFRC52$
+ * Reader on the Arduino SPI interface.
+ *
+ * When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Ardu$
+ * then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M)$
+ * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial o$
+ * will show the type, and the NUID if a new card has been detected. Note: you may see "Timeout in communicatio$
+ * when removing the PICC from reading distance too early.
+ *
