FastLED setRGB Function for Changing LED Colors

FastLED setRGB Function for Changing LED Colors




I found and tweaked the following code from Scott Kletzien in the FastLED Google+ Community.  The setRGB function threw me off at first, since I thought it worked like the HSV settings.

Here's the simplified guide to setRGB

The full function will look like the following in your sketch or code.

leds[i].setRGB(0,255,0);

Another way to look at it is   leds[i].setRGB(RED AMOUNT, GREEN AMOUNT, BLUE AMOUNT);

The amounts can range from 0 to 255.  So if you set the red to 255 and the other values to 0, you'll get red LEDs showing.

leds[i].setRGB(255,0,0); will turn the LEDs to red

leds[i].setRGB(0,255,0); will turn the LEDs to green

leds[i].setRGB(0,0,255); will turn the LEDs to blue

Using all the values at once will give you a huge range of colors.

leds[i].setRGB(241,124,200); will turn the LEDs to a pink color.

HINT:  If you're trying to find the code for a specific color, a lot of graphics programs let you pick a color and give you the RGB settings.  (I use GIMP, which is like a free version of Photoshop).
