Light Level
Find the light level (how bright or dark it is) where you are.
The light level 0
means darkness and 255
means bright light.
The @boardname@ measures the light around it by using some of the
LEDs on the LED screen.
The first time you use it, this function will say 0
.
After that, it will say the real light level.
This is because the light sensor (the part that can find the light level)
has to be turned on first.
input.lightLevel();
Learn more about how light level is detected in this light sensor video:
https://www.youtube.com/watch?v=TKhCr-dQMBY.
Returns
- a Number that means a light level from
0
(dark) to255
(bright).
Example: show light level
When you press button B
on the microbit, this
program shows the light level
on the LED screen.
input.onButtonEvent(Button.B, ButtonEvent.Click, () => {
let level = input.lightLevel()
basic.showNumber(level)
})
Example: chart light level
This program shows the light level with a bar chart on the @boardname@ screen. If you carry the @boardname@ around to different places with different light levels, the bar chart will change.
basic.forever(() => {
led.plotBarGraph(input.lightLevel(), 255)
})
