Twinkle, twinkle little star,
How I wonder what you are?
All our projects start with cardboard box. We added an #Arduino, a Red Green Blue (RGB) sensor, and section of CD Rom.
Then we coded the RGB sensor on the Arduino.

We wanted the Spectrum of the Sun. But Sun is too bright.
We attached a webcam inside to display spectrum on a screen. And we were able to see the Continuous spectrum of the Sun and emission spectrums of Fluorescent Bulbs.
