==Objective==
Here we make a simple light indicator, which classify light value in three levels—green, blue and red.

==Principle==

==Hardware Buildup==
*Setup 1：Connect CoreUSB to your PC, open program examples, select the right board (Microduino-CoreUSB) and download program through serial port.
[https://github.com/Microduino/Microduino_Tutorials/blob/master/MCookie_Tutorial/light_led/light_led.ino light_led]
*Setup2：Connect the light-sensitive resistor to A0 pin of Sensorhub and the colored LED light to D6 pin.

*Setup5：Stack CoreUSB, Sensorhu and BM.

*Setup6：Connect the battery to BM.

==Software Debuggin==
Code description: One part to acquire sensor values and the other part to control LED brightness and color change according the values.
*Sensor pin description
<source lang="cpp">
#define PIN 6
Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, PIN, NEO_GRB + NEO_KHZ800);

#define Light_PIN A0
</source>
*Light intensity pre-set value and the light can be divided into three levels.
<source lang="cpp">
#define Light_value1 400
#define Light_value2 800
</source>

*Light detection
<source lang="cpp">
sensorValue = analogRead(Light_PIN);
</source>

*The colored LED will adjust color and brightness according to light intensity.
<source lang="cpp">
if (sensorValue < Light_value1)
colorWipe(strip.Color(0, map(sensorValue, 10, 400, 0, 255), 0));
else if (sensorValue >= Light_value1 && sensorValue < Light_value2)
colorWipe(strip.Color(0, 0, map(sensorValue, 400, 800, 0, 255)));
else if (Light_value2 >= 800)
colorWipe(strip.Color(map(sensorValue, 800, 960, 0, 255), 0, 0));
</source>

==Result==
Change light intensity from weak to strong, you can see gree, blue and red in order.
