This is the first project for both of us in Arduino and 3D modelling, therefore we are just beginners and our original idea was to make a lamp in the form of an animal who emanates natural light so the options were a firefly or a jellyfish and we went with the second idea. We chose a jellyfish to embody the model of our decorative lamp because it's a beautiful little creature that naturally glows

1. Computer with Fusion 360

2. 3D printer

3. 4 RGB leds

4. 1 Arduino Uno

5. A breadboard (cut in half)

6. A pushbutton

7. 4 200 Ω Resistors

8. Cables

So, as you can see the sketch that was made first has more nature-like forms and it could be quite inconvinient to recreate it in Fusion so we modified it later for it to fit the electronics but still keep its jelly fish form.

The lamp itself is made out of 3 main bodies. The bottom one has a suport system represented by 4 constructions in the shape of "tentacles" as well as the inferior part of the "bell" that holds the Arduino and Breadbord. The middle body has the LEDs integrated and connects with the other two through box like features. The top body serves as a cover, while it's transparent quality allows the shine from the LEDs to get through and fulfill it's decorative lamp porpuse.

NOTE: It is important to know the exact measurements for the components so that you dont encounter any errors in the building after the model has been printed, so always do your research.

Simulator: Tinkercad

I used 4 RGB leds for this and each led goes in the 4 circles at the top of the jelly-fish model. The scheme is stored in the wider space above the tentacles. Each led is connected to a 200Ω resistor, this would be the average resistence for such leds, this step is very important so make sure you got your resistors on, otherwise you might burn the leds. Another important step is connecting the RGB leds only to the analog pins (the ones who have ~ near them), of course this does not apply if you are using normal colored leds. I used a normal push button that will control all the leds, the idea is for the light functions to change everytime the button is pushed (basically like some christmas lights do) and it succeded, code on the next step.

NOTE: The color of the cables I used is just for representation and each color is connected to the respective colored led, for reference.

NOTE: Rosu=red, Albastru=Blue, Verde=Green. The numbers near the names (ledRosu13) are the leds, in this case it's led 1 and 3

Now a little bit about the functions:

'ON BLUE'(ONB)-all the leds turn blue simultaniously and stay on until the next function;

'ON WHITE'(ONW)-same as the previous one but in white;

'ON MAGENTA'(ONM)-same as the previous one but magenta;

'MAGENTA BLUE'(MB)-the leds turn on in a magenta color, stay on 5 seconds, turn off for 1 second, then turn on again in a cyan/light blue color and the process repeats;

'BLINK'-all the colors turn on and off very fast one after another (blue->cyan->green->yellow->red->magenta);

'BLUE FADE'(BF)-self explanatory, the leds turn on blue slowly and also slowly turn off and so on;

'DIFFERENT COLORS'(DF)-also fade but with each color, the colors slowly fall into one another;

'OFF'-all the leds turn off.

We had a lot of fun working on this project and hope that someone can be inspired from it. Thank you to GGIT for guiding us troughout the process, we learned a lot :)

And if someone wants to try and re-create this project, you can always add or take out stuff, nothing is set in stone, get creative!
