Using an Arduino to write programs to an 8x8 WS2812B LED array. For those who don't know, LEDs like the WS2812B actually contain 3 LEDS and a controller chip. The LEDs, one red, one blue and one green, can be turned on with varying degrees of brightness to act like pixels in a screen, creating any color you want. The programming possibilities are endless.
I'm actually almost done with this part of my project, but I want to get it to 100 percent before sharing the whole thing. For now, here's some of the steps I'm going through to make it.
My goal is to make a full road standard that I can continue to expand upon in the future. The lane width conforms to the New Hashima road cube standard, so it is possible to connect to such cubes. For side roads and alleyways I am using painted road markings, but the main roads will be lit by an array of addressable WS2812b RGB LEDs, thus the clear markings on this section of road. Each 32 stud long section is kept physically and electrically separate via connectors between the sections, so they can be removed easily in the future if need be. The RGB LEDs are run by an Arduino built into the road module. The LEDs can change color, turn on and off, fade in and out and basically anything you can imagine, and they can run a long program that allows their behavior to change over time. My current section of elevated highway consists of 20 sections like this one.
The road system and its markings are a mix of influences from around the world. This 'caution' marking is Japanese and uses the blocky lettering of some Japanese lane markings.
NeoPixel color led test. Done with the FPGA controller for my Fischertechnik project. Only one drive signal need to drive up to more then 256 leds, each with different 24 bit RGB color. Stream works at 800 KHz. Just now the software drive 64 leds for the project but there is no limit for the max number of leds.
Works just super fine!
Multiple modes are available such as flashing, on / off, alternate color. Each led has 4 different colors stored in a ram. This is primarily useful for servos. So you can view multiple positions of the servo via a color. The program can still customize any desired color during run mode. Because an FPGA works in parallel, this does not affect the load of the other program parts. The NeoPixel drive has its own hardware part inside the FPGA, which makes the timing perfectly constant.
The used NeoPixel LED is the WS2812B.
Made with:
144 WS2812B LED Strip - Just order the cheapest WS2812B Strip you can find, don't pay 2x on Adafruit
Blinkytape Control Board - Arduino compatible ATMega based board that drives/animates the LEDs. An arduino can be used if more memory is needed.
A USB power bank is used to power the Blinky Tape Control Board & LEDs, though a 8 x AA holder and a buck converter also worked well.
The frame is made from square aluminum tube with a 3 way tee connector. A ball plunger was added to make the handle easily removable.
A diffuser can also be added to not have the individual LEDs show in final pictures.
PatternPaint is the program used to program the Blinky Tape Control board with the various patterns and animations.

The PL9823 is similar to the WS2812B, but comes in the typical 5mm LED dome package.
This makes it very suitable for use in RC cars.
The WS2812B LED on a breakout-board for convenient mounting.
The WS2812B is an RGB LED with a built-in shift register like controller. It has 4 pins: GND, Vdd, Data-in and Data-out. With only three wires going from LED to LED, one can control each LEDs color and brigtness individually.

1. Product Overview :
SK6805-2427 is a smart LED control circuit and light emitting circuit in one controlled LED source,
which has the shape of a 5050 LED chip. Each lighting element is a pixel, and the intensities of the
pixels are contained within the intelligent digital interface input. The output is driven by patented
PWM technology, which effectively guarantees high consistency of the color of the pixels. The
control circuit consists of a signal shaping amplification circuit, a built-in constant current circuit,
and a high precision RC oscillator.
There are two types of lights used on my elevated highway. This is an addressable WS2812b LED These were used for most of the road markings and can be programmed to do basically anything you can imagine a light doing. All the LEDs were purchased 'raw' on a reel. These LEDs are actually 3 LEDs in one, a red, a blue and a green LED are set in the package along with a microcontroller. The series resistance is built into each LED, so I only had to add wires to these. There are 4 wires. 5v in, ground, data in, and data out. I know there are many off the shelf modules and strings out there, but I estimated the 10 baseplate long section I wanted to build would need about 430 LEDs at a minimum. Buying these individually or even in kits wasn't an option for me. Moreover, they also couldn't just be on a premade string. Their spacing and positioning has to be carefully controlled. I also wanted to concentrate the light up into the clear sections of the road and away from other directions and to diffuse the light a bit, while keeping the road thin. So, each LED was affixed to some LCD screen backlight diffusion plastic with hot glue, and the back of the whole thing painted to keep the light from bleeding out the back. This also allowed more surface area to attach the lights to the underside of the road.
It's hard to read from the Aliexpress listing, so here's the crudely drawn pinout of this wonderful LED.

I got a set of macro lens for my iPhone, and I'm pretty impressed. When I first popped it on to my phone I looked at my desk for something small and found this WS2812B LED. No prep, no special lighting and hand held.
The RGB LEDs are a very tight fit in the 12mm holes, so I'm taking a break from pressing them in because it's making my fingers hurt!
