Video – tips with WS2818b

Hello everyone,

as promised here is the video explaining how I soldered my LED’s to create the display in my worldmap clock project.

As stated in the video, the module used is Ws2818B which are individual RGB leds individually controllable .

I bought them by 100 on Banggood for about 15€

I found a lot of useful tips on how to power it and use it properly on Adafruit’s website (which also the provider of the library to control it) Adafruit Uberguide for Neopixel



Arduino SmartClock – Nano version

After having successfully created a SmartClock with Arduino, I decided to do it again but smaller !

As I want this project to be more colorful, I found an alternative to simple RGB led. The module is called WS2812 and it is simply awesome !

The modules are fairly easy to use and are connected on cascade. You can simply control the color of every LED separetely.

Description of the module : here


One powerful WS2812

For now, I’m using the Arduino Uno for prototyping, but in order to have everything in a small box I’ll use the Arduino Nano Pro.

Here is what it looks like now :
