Color Input

Provides interfaces to an I2C-connected Color Input sensor.

The bb_port pin is used in addition to the I2C port to control the LED on the color sensor.

• color_number(): Returns a value from 1 to 9 that represents the color the sensor is detecting.

The numbers represent the colors per the following mapping:

1: Red

2: Green

3: Blue

4: Cyan

5: Magenta

6: Yellow

7: Black

8: White

9: Gray

• red(): Returns a value from 0 to 255 that represents the intensity of the RED color level being detected.
• green(): Returns a value from 0 to 255 that represents the intensity of the GREEN color level being detected.
• blue(): Returns a value from 0 to 255 that represents the intensity of the BLUE color level being detected.
• gray(): Returns a value from 0 to 255 that represents the gray level being detected, where 0 is black and 255 is white.
