Introduction: Light Pollution
This is a project about light pollution, which I simulate a micro world under the water.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step1
I bought these 3D models to fold it by myself, it was really hard to fold it and would hurt your fingers.
Step 2: Step2: Soldering
Soldered the wires and LEDs together, and use tape to make sure to cover the notch in order to make these waterproof.
Also, solder the ultrasonic sensor with the wires, we do not have to tape it, we will stick the sensor outside of the container.
Step 3: Step3: Arduino
Step 4: Step 4: Insert
Stick the artificial grass and tree in the bottom of the container.
And insert LEDs inside the 3D models.
Then, stick the Arduino and breadboard outside of the container.
And try to flatten the wires which inside of the container, and stick on the grass.
Also, the Ultrasonic sensor should go around the container to the front.
Finally, the container should fullfill with water. And drop a drip of dark blue liquid pigment inside.
