You can observe this scene: colors of ve LED will gradient
consistently.
Extended application: Based on Chainable LED Library
[https://github.com/pjpmarques/ChainableLED], we have designed
this demo: RGB color varies with the temperature measured by
Grove - temperature. The RGB color vary from green to red when the
temperature is from 25 to 32. The test code is shown below. Do it if
you are interested in it.

33 if (hue>=1.0 && up)
34 up = false;
35 else if (hue<=0.0 && !up)
36 up = true;

1 // demo of temperature -> rgbLED
2 // temperature form 25 - 32, rgbLed from green -> red
3 // Grove-temperature plu to A0
4 // LED plug to D7,D8
