/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* The LED chipset is WS2812B RGB  Number of LED is */
    /* 20  Digital output is D5  write a code:  led fade */
    /* in and out randomly, increments 5.  set fade in */
    /* value at 0,  set fade out value at 255  set fade */
    /* time from 0 to 255 at 5 seconds  use only warm */
    /* colors */
/****** END SYSTEM REQUIREMENTS *****/


/********* User code review feedback **********
#### Feedback 1 ####
- The colors for each led are random, use warm colors only
#### Feedback 2 ####
- the 20 led fade in and out at the same time. this should not be.
 each single led should fade in and out separately and randomly
