Random

shortname: grnd
How: random8()
What: Returns the value of a random number from 0 to 255, so this function is an 8bit random number generator.
Example: Inputting led_color(num,1,random8(),random8(),random8()) will set the LED color of the control element, each time a value change happens, the LED color of each button press will be randomized.
A fun example would be a code for randomizing LEDs on a Grid module with 16 LEDs:
```
for x = 0, 16 do
    r = random8()
    g = random8()
    b = random8()
    led_color(x, 1, r, g, b)
    led_color(x, 2, r, g, b)
end
```
If you'd want different values for the two layers just double the whole variables section like this:
```
for x = 0, 16 do
    r1 = random8()
    g1 = random8()
    b1 = random8()

    r2 = random8()
    g2 = random8()
    b2 = random8()

    led_color(x, 1, r1, g1, b1)
    led_color(x, 2, r2, g2, b2)
end
```
This could be useful for encoders for example, that can have a different (layers 1+2 both active) color when you rotate an encoder while also pushing down on it.
