Hi  
Does anybody know about work done to control an RGB LED Strip with effects?  
Like a Knight Rider (red bar bouncing from one end to the other) or a Progress Bar or any other?

How are you controlling your LED strip?

There are quite a few Arduino code Knight Rider examples on the web, you might be able to adapt their algorithm to suit your own setup.

If you have a Raspberry Pi, then you can control strips of Neopixels using Node-RED and

Making a Knight Rider effect is certainly possible but not done it myself

Alternative is to use the exec node to call say, a Python program, that already does effects

If you use an ESP32 to control the lights, then you can use the excellent [WLED](https://kno.wled.ge/) firmware to do all kinds of animations etc. Which can easily be controlled via a web interface OR via a node red dashboard.
