Specification

Controlling an LED strip with individually controllable RGB LEDs. This stuff is awesome.

The SJ individually contollable RGB strip contains a bunch of ws2801 ICs.

These are controlled over a simple data an clock setup.

The ws2801 is really cool !

Each IC has its own internal clock so that it can do all the PWM for that specific LED for you.

Each IC requires 24 bits or " greyscale " data. This means you can hve 256 levels of red, 256 of blue, and

256 levels of green for each RGB LED.Really granular.

To control the strip , you clock in data continually.

Each IC automatically passes the data onto the next IC . Once you pause for more than 500us, each IC

'posts‘ or begins to output the color data you just clocked in .

So, clock in (24 bits *32 LEDs=)768 bits,then pause for 500us.

Then repeat if you wish to display something new.

You will need to connect 5v/GND from the Arduino ( USB power seems to be sufficient).

For the data pins, please pay attention to the arrow printed on the strip.

You will need to connect the end that is the begining of the arros(data connection).

We have a 4 -pin connection:Red=5V,Blue=CLK,Green=DAT,Yellow=GND.

We have female head =Output, male head=Input.

We have non-waterproof , there are 3 kind waterproof methods: Dripping glue , PVC/Silicon Tube , Dripping glue+PVC/Silicon Tube.
