# Reflected light calibration
|
|
|
|
The ``calibrateLight`` blocks allows you to calibrate the reflected light of the color sensor in one block. Start the block and move the sensor over the dark and bright surface; then stop moving it.
|
|
|
|
```blocks
|
|
sensors.color3.onLightDetected(LightIntensityMode.Reflected, Light.Dark, function () {
|
|
brick.showString("dark", 2)
|
|
})
|
|
sensors.color3.onLightDetected(LightIntensityMode.Reflected, Light.Bright, function () {
|
|
brick.showString("bright", 2)
|
|
})
|
|
console.sendToScreen()
|
|
console.log("move color sensor")
|
|
console.log("over DARK and BRIGHT color")
|
|
console.log("and stop moving when done")
|
|
console.log("press ENTER when ready")
|
|
brick.buttonEnter.pauseUntil(ButtonEvent.Pressed)
|
|
sensors.color3.calibrateLight(LightIntensityMode.Reflected)
|
|
brick.showValue("dark", sensors.color3.threshold(Light.Dark), 4)
|
|
brick.showValue("bright", sensors.color3.threshold(Light.Bright), 5)
|
|
forever(function () {
|
|
brick.showValue("reflected light", sensors.color3.light(LightIntensityMode.Reflected), 1)
|
|
})
|
|
``` |
