On the Uno and\r\n  Leonardo, it is attached to digital pin 13. If you're unsure what\r\n  pin the on-board LED is connected to on your Arduino model, check\r\n  the documentation at http://www.arduino.cc\r\n\r\n  This example code is in the public domain.\r\n\r\n  modified 8 May 2014\r\n  by Scott Fitzgerald\r\n */\r\n\r\n\r\n// the setup function runs once when you press reset or power the board\r\nvoid setup() {\r\n  // initialize digital pin 13 as an output.\r\n  pinMode(13, OUTPUT);\r\n  Serial.begin(115200);\r\n}\r\n\r\n// the loop function runs over and over again forever\r\nvoid loop() {\r\n\r\n\r\n  Serial.println(\"!!!!!!!!!!!!!!
