FLORA Color Sensor
Your projects can see in color! This board is based around the
TCS34725, which has RGB and clear light sensing elements.
This board (see
Figure 3-12
) has an infrared blocking filter,
which means you'll get much truer color than with most sen-
sors, since humans don't see IR. The color sensor is great for
making a scarf with LEDs that change color to match the rest of
your outfit, for example.

FLORA color sensor
To make sure you get consistent color, the color sensor has a
neutral white LED to illuminate what you're trying to sense and
give a consistent reading in diverse lighting conditions. The LED
can be easily turned on during sensing and turned off afterward
to save power.
