I wired these goggles up, I have a simple animation move through the string at the moment. I have no idea what I am doing. I am trying to emulate the First animation here ( https://twitter.com/OfficialRezz/status/738099924231983104 )

Check your code, looks like the last two pixels aren’t lighting up.

Here’s two sketches that might give you some ideas.

Just work on getting your pattern going on the first half of the strip, one side of glasses, and then you can copy that to the other side. When coping the order can be the same or reversed so both sides spin the same way or opposite directions.

Can I set different groups of dots to spin at different speeds, The inner ring being smaller spins faster.
Also cant seem to get a dot to continually start from LED25 to LED41.
I’ll keep trying

You sure could. You could use a different number of milliseconds in three different EVERY_N_MILLISECONDS blocks.

Matthew_DeFaveri · July 13, 2017, 6:10pm

oh yes I see! one more question I cant seem to figure out. I have a group of dots to start at pixel 27 and end at pixel 40, how do I get them to start at pixel 25 after they hit pixel 40?

marmil · July 13, 2017, 6:14pm

Not sure how you’re doing it, but I might do something with an IF statement. If position equals 40 then subtract 15.

I too, am a big fan of Rezz!

Those are great! I’m currently putting together something similar only in single, medallion form. How did you wire the inner 4 LEDs? I’m not looking forward to that. As for your 27 to 40 problem, you might want to look into using CRGBset (or CRGBarray) which will let you treat your LEDs as a 2 dimensional array. That way, if the 27 - 49 group is the 3rd set of LEDs, you would refer to the LEDs as leds[3,x] and put x through a for next loop from 0-13 to have it go across that section of LEDs. You can also use fill_solid/gradient/rainbow on each section so they can all be different colors.

Matthew_DeFaveri · August 6, 2017, 6:13pm

Hey, I wired the 4 inner led with some non insulated wire to keep the form factor small, then insulated it after i was done with some hot glue. For the animations i managed to make it work with allot of help haha.
