4 | + Turns an LED on for one second, then off for one second, repeatedly. | |
5 | + | |
6 | + Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO | |
7 | + it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to | |
8 | + the correct LED pin independent of which board is used. | |
9 | + If you want to know what pin the on-board LED is connected to on your Arduino | |
10 | + model, check the Technical Specs of your board at: | |
11 | + https://www.arduino.cc/en/Main/Products | |

2 | -This directory is intended for project header files. | |
3 | - | |
4 | -A header file is a file containing C declarations and macro definitions | |
5 | -to be shared between several project source files. You request the use of a | |
6 | -header file in your project source file (C, C++, etc) located in `src` folder | |
7 | -by including it, with the C preprocessing directive `#include'. | |
8 | - | |
9 | -```src/main.c | |
10 | - | |
11 | -#include "header.h" | |
12 | - | |
13 | -int main (void) | |
14 | -{ | |
15 | - ... | |
16 | -} | |
17 | -``` | |
18 | - | |
19 | -Including a header file produces the same results as copying the header file | |
20 | -into each source file that needs it. Such copying would be time-consuming | |
21 | -and error-prone. With a header file, the related declarations appear | |
22 | -in only one place. If they need to be changed, they can be changed in one | |
23 | -place, and programs that include the header file will automatically use the | |
24 | -new version when next recompiled. The header file eliminates the labor of | |
25 | -finding and changing all the copies as well as the risk that a failure to | |
26 | -find one copy will result in inconsistencies within a program. | |
27 | - | |
28 | -In C, the usual convention is to give header files names that end with `.h'. | |
29 | -It is most portable to use only letters, digits, dashes, and underscores in | |
30 | -header file names, and at most one dot. | |
31 | - | |
32 | -Read more about using header files in official GCC documentation: | |
33 | - | |
34 | -* Include Syntax | |
35 | -* Include Operation | |
36 | -* Once-Only Headers | |
37 | -* Computed Includes | |
