Finally this project is done!
I call it "Surprise Box". The Box I created has several layers.
The lower layer is used to hide Arduino and battery. I also make a hold at the bottom of the heart, in order for a LED light to go in.
My original idea was to plant some moss in the box as a background. However, I used some dry pine tree leaves instead.
Could be and do not think that our action can actually influence the environment.
And the plant / moss part of the project conveys my idea that personally, I think plants have "hearts", or their feelings too. So when people cut a tree, it can feel the pain. The flowers on the heart and the butterfly symbolize the beauty and purity of the nature. The nature provides all these enjoyable sceneries to all the livings in this world, and they are something that we need to treasure and protect.
I used SLS to print it. The powder used is PA2200, which is a Nylon material, water resistant.
