EASTER Egg with NeoPixels WS2812B made from cardboard

.

.

Soon there will be EASTER and decorations are getting put around the house worldwide as it is tradition since ages to do so. That’s also the time for tinkerers, makers to GET some new ideas. Well, I thought on a project which everybody could do without having a 3D-Printer NOR a Laser cutter at home and not having access to them on other places. SO, I tried out to create a EASTER-EGG from cardboard using an Arduino UNO and Neopixels…

I recently bought 1 Meter of Neopixels WS2812B with 60 LEDs and tried it out while wife was looking at it and she told me if that wouldn’t be an idea for making a Easter-Decoration, e.g. an egg. I took that challenge and a day later it was working, LOL 😉 I used a 3,5 mm thick cardboard from a red wine box which was stable enough to create the project.

I copied an image (the orange egg) from an Easter-Egg which I found on the internet (license-free), glued it on the cardboard and cut it out.

 

You may have a look on this Tutorial to know a bit more about the handling of Neopixel LEDS, please:

The project itself by cabling is actually VERY easy, ONLY 3 wires, the MOST work is on the mechanical part by cutting the cardboard, painting, soldering the Neopixels WS2812B strip and to put everything into a box with the necessary parts, while drilling, etc. WE will see this in detail by following PICS… But first let us solder and interconnecting the Neopixels LEDs strips, you need to follow the arrows on the strips to connect each of the LED strips, thus meaning: see PICs please:

Follow the arrows

.

.

Once all the LED strips are interconnected, you can connect the other 28 LEDs to the point marked with “START” and connect them to the ARDUINO UNO board through a screw terminal to make the first tests. Please check the tutorial below with the code for the How-To:

IF everything is working, hopefully, we can go for the integration of the components into a housing. TIP: prepare the ARDUINO UNO (NANO) already with the code uploaded and test after each LED strips connected to make sure it will work!! it’s BETTER to invest time for NOT later having trouble and NOT knowing from where the fault comes 😉

Well, you have seen NOW the different mechanical steps and the soldering inside the housing, that’s the preparation, now we have to connect as well the Xmas star to the Arduino… We will use a 3 x 0.75 mm² cable to do so, find below, please, some PICs which show you the How-To, as well as the components with links to purchase them (I used AMAZON.DE), feel FREE to purchase them where you want:

.

And here the MOST important to make it work, the code:

The code will get downloaded and copy it, then paste it into the Arduino IDE.

.

This is how the code will look and where you can (MUST) modify it, see PIC below please:

You need ALSO to download and to install the “FastLED.h” Library

Download the  “FastLED.h” Library here in case of that you will NOT find it in the “Library manager”:

Check also, please:

Have fun and stay tuned for next projects 😉
