API for Grove light sensor. More...

Detailed Description

The Grove light sensor detects the intensity of the ambient light. As the light intensity of the environment increases, the resistance of the sensor decreases. This means that the raw value from the analog pin will be larger in bright light and smaller in the dark. An approximate lux value can also be returned.

    // Create the light sensor object using AIO pin 0
    upm::GroveLight* light = new upm::GroveLight(0);
    // Read the input and print both the raw value and a rough lux value,
    // waiting one second between readings
    while( 1 ) {
        std::cout << light->name() << " raw value is " << light->raw_value() <<
            ", which is roughly " << light->value() << " lux" << std::endl;
        sleep(1);
    }
    // Delete the light sensor object
    delete light;
