If you look at the code for the “ColorPalette” example, the line “leds[i] = ColorFromPalette( currentPalette, colorIndex, brightness, currentBlending);” and set “i” to the value of the LED you want to control then only that one LED will be turned on. Remember that the LEDs start counting from 0.

Playing around with the VCC-GND pico “clone” board which comes equipped with 1 WS2812B RGB LED and could not get it to work. After many frustrating attempts, I found a post that mentioned the pads marked “RGB” (poorly silk screened – looks more like a resistor marking!) on the board must be soldered together for the LED to be connected to GPIO23 as it is shown in the limited documentation for this board. Once that is done, viola it works!

If you answer Malisa’s question I will benefit from it too. Thanks again

Random Nerd Tutorials is by far the best. Their examples are well written and always work.

Thank you Sampo…. I thought this might never get answered (it is over a year ago…. 😊 ) so I do appreciate your answer…

I’ll give it a try!

Thank you again
