Aquarium kit assistance

Light system and pr

Made by Xi

A simple prototype that could be applied to aquarium kit. In the daytime (while the light is adequate), there is no light; when the light gets darker - in the evening, the light color switches randomly among red, green and blue; when it gets even darker - coming to night, the light color varies to any color randomly. (P.S. The color looks soft and suuuuuuuuuuuuuper cute in the dark!!!!!) Another function of the prototype is the pressure. When too much pressure is applied to the sensor because of the fish's metabolism, a line of red lights would be turn on for warning.

Goal:

1. Turning on the lights inside the aquarium kit automatically when it's getting dark, and makes the color varies at night for aesthetic purpose.  

2. When the pressure inside the aquarium kit gets high, turn on several red LED for warning.
