Gro Egg Take Apart

For this project, we took apart a Gro Egg—a night light that lets you know the temperature of your baby's nursery through temperature readings corresponding to light colors. The input was a temperature sensor, the processing was a component that read the temperature range, and the output was the temperature readout and the corresponding colored light. Some interesting things about this Gro Egg were:
-The temperature sensor is not inside the egg. It is part of the charging cable that plugs into the egg.
-There are multiple lights that light up different parts of the egg. There is a row of lights underneath the LCD screen that is responsible for lighting it up with the correct color as well as the bigger lights that light up the whole egg.
-The clear resin backing (which we took off of the LCD screen) allows it to be backlit from below, spreading the reach of the shorter row of lights.
-The temperature range (over 75, 67-75, 61-67, under 61) determines the color of light (red, orange, yellow, blue).
