Simple, that’s the way to begin. And we get some useful sequences out of it.  On this page, we have

The World’s Shortest Sequence

One line of code. That’s it!

//world's shortest sequence
//starts dark, fades up
//repeats continuously
//takes a moment to turn on the first time

@300ms chn1 = fade from 100% to 0% for 300ms   //turns chn1 On then fades Off

//falls through to end and replays

Try adjusting the two 300ms numbers differently to control for how long the LED turns off or if it does at all. How would you speed it up to a frantic flutter or slow it down to almost imperceptible waning light?

Alien Glow

2 to 3 lines of code!  Smooth, gradual fades.

//Alien glow
//Two line version
//doesn't fade to 0%, we chose a little persistence at 4%.
//doesn't reverse instantly, we made a short 100ms hesitation
//it takes two seconds to get started

@2000ms chn1 = fade from 4% to 100% for 1900ms 
@4000ms chn1 = fade from 100% to 4% for 1900ms

//falls through to repeat

 

//Alien Glow
//Three line version
//exactly the same as two line version, except it starts instantly.
//doesn't fade to 0%, we chose a little persistence at 4%. 
//doesn't reverse instantly, we made a short 100ms hesitation 

        chn1 = fade from 4% to 100% for 1900ms
@2000ms chn1 = fade from 100% to 4% for 1900ms
@4000ms //wait for 2nd fade

//falls through to repeat

 

Sequences on this page used the following syntax. Refer to the help file in Sequence Composer or the tutorial chapters for more information.
