12mm Diffused Flat Digital RGB LED Pixels (Strand of 25)

Post by anjemalo »

Hello:
I need some help for use with 12mm Diffused Flat Digital RGB LED Pixels.

1- How can I can keep one LED lit all the time? I need to light on one led at a time when I need it.
2.- How can I turn off all LEDs?

I have seen the code example, but I don't find this information.
More examples code, please?
thank you very much

The pixels are individually addressable. To light one led at a time, call SetPixelColor(pixel, color): where 'pixel' is the number of the pixel you want to light and 'color' is the color you want it to be. To turn a pixel off, set the color to 'black' (see below).

Color is specified using the color(red, green, blue) function: where red, green and blue are numbers between 0 and 255.
color(25,255,255) = white
color(255,0,0) = red
color(0, 255,0) = green
color(0,0,255) = blue
color(0,0,0) = black

Other color mixes are possible. Experiment!
