looking programmer to make a code.

Hi everyone . looking programmer to make a code.

I need to make Motion Activated Stairs using WS2812B LED Strip and Mega or Uno

  1. When is PIR motion sensor ( of course is two sensors on the top and bottom of stairs ) was activated all led is white: white color effect :like on this video:

but with fade-in effect. Make a option to change speed

fade-in effect: https://www.youtube.com/watch?v=fWynJGzJGOw

when after 3 sec or so need to change effect like on this video: go till 0.46 sec to see the effect:

The effect will start from the side of is PIR motion sensor was activated. This effect will stay about min or so ( make possible to change the time ) and when disappear with fade-out effect

Also find this sample ( add rainbow and fade effects ):

  2. Speed to change color 3.Color random or I can add as many colors as i want.
