Albert Einstein once said: "I have no special talents. I am only passionately curious."
Curiosity is the birthplace of Science.
It feels good to be curious and to learn.

Poll: How many of us learned the children rhyme?
Twinkle, twinkle little star,
How I wonder what you are?
Twinkle, twinkle little star,
How I wonder what you are?
And how many grew up and ended up learning more about Stars?
Awesome results from the Polls! Many of us continued to stay curious about Stars!
Us too!
We dreamed of a device which would answer:
⭐️What stars are made of?
⭐️How hot the stars are?
⭐️How old the stars are?

So we started with Pencil and Paper:
Drew and wrote down what we had in our mind - Our questions, our Ideas

Stars are far away. How do Astronomers learn so much about them?
We researched. And found that the answer was Star Light.
We can find temperature, age of stars, what are they made of by studying the light from them.
Rigel is blue and is hotter than Betelgeuse which is Red!

We experimented and found CD Rom can break light into component colors. We decided to add a Red Green Blue Sensor to our device to estimate the temperature.
From the Spectrum, we can find what stars are made of by looking for certain lines.
So we improved our design!

And then we started making our Device.
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.

And tested the sensors on familiar objects and colors for calibration.
It worked!
We were able to get Luminosity, Temperature and RGB Color components of brightly lit objects.
We added a Star Spectrum Chart on the side to relate temperatures with those of bright stars.

We were not satisfied with #GalacticBot
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.
