Introduction: RGB 7-segment Display Clock With WS2812B

I am a 16 years old that loves electronics and especially arduino.

Just another seven segment LED clock.

Step 1: Materials (Off the Shelf)

Hardware:

- WS2812b led strip (60leds/m) Click here

- ESP8266 Click here

- Electrical wires Click here

Tools:

- 3D printer (generic)

- Soldering station

Step 2: Material (3D Printed)

You have to print the following parts: (Some parts need to be printed a couple of times)

- 4 x digitTop (must be white)

- 4 x digitMiddle

- 4 x digitBottom

- 1 x dotsTop (must be white)

- 1 x dotsMiddle

- 1 x dotsBottom

- 1 x cover

- 1 x stand

The parts can be downloaded using this link

Step 3: Painting

Now that everything is 3D printed, you can start giving color to your 3D prints. Make sure that you don't paint the digitTop and dotsTop because they have to diffuse the light, if painted it won't let any light trough. I went for a matt black color, but you can choose every color you want!

Step 4: Glue the Diffusers in Place

After the coat of paint, it is time for the assembly of the clock. We are gonna start with glueing the diffusers (dotsTop and digitTop) in place. I used some hobby glue for this, but you can use any glue you want.

Start by putting a layer of glue on the digitMiddle and dotsMiddle and then gently put the diffusers in place. Let the glue dry and now they are nice and neatly glued into place!

Step 5: Cut the LED Strip to Lenght

The next step is to cut your LED strip to lenght. For this clock we will need 28 pieces with 2 leds and 2 leds on its own.

Step 6: Stick the LED's to the Bottompiece

Now it is time to stick the LED's in place. We'll have to stick them on the digitBottom and the dotsBottom. After sticking them, I recommend to use some clamps to make sure they are sticking well.

Step 7: Soldering

In the next step, you have to solder all the LED's together. Make sure you use the right order of the segments, because if not correctly ordered, the code won't work.

Step 8: Place Everything in the Holder

Now that every part is finished, we can put everything in it's place.

Step 9: Connecting Everything to the ESP8266

The connections:

1. 5v to 5v

2. gnd to gnd

3. data pin to D2

(this is fairly easy because we only have 2 components the LED strip and the ESP8266)

Step 10: Uploading the Code

Right now everything is done. That means it is time to upload the code!

1. Download the rgbLed.ino file using this link.

2. Open it using the Arduino IDE

3. Choose the ESP8266 and upload the code

Now everything should work and you can show your new creation to all of your friends!

    Love this one! Such a cool way to 3D print the casing... you got my vote!
