NeoPixel 106 - Multiple strips 

It pulls out variables in the arrays. I think I have a video on arrays.

It's a common expression in programming, it executes the code that's inside of the "for loop", with each iteration increasing a by 1. First set A=0 and code executes with that value, then it sets A to be A+1 (0+1) and executes the code again, and so on, until it reaches the max value allowed for A, like 3 here, since the for loop defines that A

Just as the video shows. You can either toggle the output pin / create multiple neopixel objects / create a neopixel object array.

@@brakthehun hii sir like this sir ? Adafruit_NeoPixel strip[20 = { Adafruit_NeoPixel(50, 0, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 1, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 2, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 3, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 4, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 5, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 6, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 7, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 8, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 9, NEO_RGB + NEO_KHZ800),, Adafruit_NeoPixel(50, 10, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 11, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 12, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 13, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 14, NEO_RGB + NEO_KHZ800), Adafruit_NeoPixel(50, 15, NEO_RGB + NEO_KHZ800) }; but this way doesn't work more than 10 neopixel strips can you please share the currect code to derive more than 10 neopixel strips ?

@@Anilkumar-co9hl If you are using an Uno or a Nano,, it will not have enough memory to support all those objects at that size. Try setting your LED Count to,, like,, 12 and see if all the strips light up.

I know,, right?? This was at 2am with an old mic. I may redo these one day.

Yes!! Same program,, same pins!!

@@brakthehun thanks ;)

The delay is minimal and based on the amount of neopixels. Even with 1 strip,, there is a delay while broadcasting to the strip.

@@brakthehun Yes, you are correct. However, the 'show' function is busy-waiting for too long. Strip 2 is displayed significantly after 'strip 1' is printed. 'Strip 1' and 'Strip 2' will not show the same results at the same time.
