Usage

import LightKit
let lk = LightKit()! // May be nil if it failed to open I/Os.

Note : Most methods and properties are returning optional as I/Os requests may fail if sensors and controllers could not be found.

Ambient light sensors

let lightSensorsReadings = lk.lightSensors
print("Left sensor: \(lightSensorsReadings?.left).")
print("Right sensor: \(lightSensorsReadings?.right).")

Display

print("Display brightness is \(lk.displayBrightness)")
lk.setDisplayBrightness(0.8) // A value between 0 and 1.

lk.setDisplayPower(false) // Put display to sleep
lk.setDisplayPower(true) // Wake up display

lk.setKeyboardBrightness(0.8) // A value between 0 and 1.
