so many mistaken ideas, difficult to know where to start!
it is a shame to find so many of your answers on this forum which are1. irrelevant,2. self-serving,3. devoted to telling people they are dumb.
I thought a forum was where people went to look for help.
Paul__B told you: ... Yet you chose to attack me.
The thing that is of concern is signal distortion on the wires over the distance. That will be your enemy.The longer the wires, the more distortion you can get in the signal.The voltages can vary and you can pick up noise.
As I understand it, Neopixels are individually loaded with their RGB configuration, then all turned on. I recall reading that they operate with a 400kb/sec. data stream.
So suppose that I want to set groups of three Neopixels under separated lenses, with a total of six lenses about 4 feet apart. Can any expert out there tell me if such an arrangement would work? If not, is there any way to slow down the data rate to the neopixel strand?
If the wire is too long, the farthest pixel may be dimmer.
