Your video quality is pretty good, im surprised you don't have more subs. Thanks for the ideas!

Excellent Tutorial!! How would you modify this code to light up a group of LEDS (for example only 3) so that the position of those 3 LEDs that are "on" would track the position of the slider - moving Left or right as the slider moves?

I have an issue using with neopixel strip. Sometimes the last led flickers. How do I correct this. Would I need to use the fastled neopixel library?

Hi, thank you for the video! Very helpful. I am trying to make a simple circuit, without an arduino/coding.

I have a 5v usb power bank to supply current for a 5v led cob strip.
I want to add in a slide or knob potentiometer to regulate voltage going to the led strip (to control brightness).
Is this possible? Do I need to include resistors, even if the usb power bank only outputs 5volts?
Thank you.

i have a question if i connect multiple potentiometer will the strips react every potentiometer

U didn't show the wire connections to the LEDs
