it can be a status indicator or serve as an ornament. It can change the color and brightness level
can be controlled sequentially as an addressable LED strip
LED indexing goes from 0 to ((number of LEDs) - 1)
component name - led

methods:

• led.setColor(index, color) - sets the color of the LED
• led.setGlow(index, multiplier) - sets the LED brightness multiplier from 0 to 1 (usually visible only at night)
• led.getStripLength():number - returns the number of LEDs in the chain

            local rainbows = 1 --the number of rainbows on the strip

local colors = require("colors")
local leds = getComponent("led")
local count = leds.getStripLength()

function callback_loop()
    local offset = getUptime() / 8
    for i = 0, count - 1 do
        leds.setColor(i, sm.color.new(colors.hsvToRgb((((i * rainbows) - offset) / (count - 1)) % 1, 1, 1)))
    end
end
