| Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO | |
| it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to | |
| the correct LED pin independent of which board is used. | |
| If you want to know what pin the on-board LED is connected to on your Arduino | |
| model, check the Technical Specs of your board at: | |

| delay(400); // wait for a second | |
| COUNTER = COUNTER + 1; | |
| // after baud rate is set we can open port monitor (rightmost button in arduino IDE) | |
| // and set it's read rate same as arduinos write rate. then we can print in java-like style :) | |
