First of I'm a noob so I don't understand why the more leds the slower
is their a way to speed up the animations on a length of 900 Leds?
Because all the data has to be sent to the strip. The WS2812 has strict timing requirements on the data bits, the data line must be held at a high state and a low state for a fixed amount of time. It is the ratio between the time the data signal is high and low that defines if it is interpreted as a logic one or logic zero. So the more LEDs the more data and the slower it is.No.
If you tell a friend to give you $1 how long would it take.If there were 899 people that had to first get the request, how long would it take to get $1 if your friend was at the end of line of people.
connected together in series around the roof line of my house.
No problem, it's just a question of length of wires.
I'm not sure I understand what you mean.
and it's working perfectly.
If the Arduino is located at the center of strip number 5, the maximum wire length is 1.66/2 + 3*1.66 = 5.8m.
I didn't do any oscilloscope measurement as you anticipated, because I don't need to do it.
I have three 5M steps of Ws2812b leds
You do need to do it if your are going to use the word "perfectly " to describe how your LED rings work. Otherwise you can just say it works for you.
I don't see how your numbers add up to 15 meters.
In the case of 9 short strips,
