Keep in mind that often WS2812 strips are offered as WS2811 strips – different name, same thing. Now that we know the basics and the things to look for, you should be able to order the right strip. The LEDs need to be “told” to be ON, so without data feed your LEDs will remain OFF. Note : Simply connecting +5V and GND will at best flash up your strip for a fraction of a second. It’s important to pay attention to the arrow, if you use your strip in the wrong “direction”, it will not work. The arrow printed on the strip indicates the data flow direction.Įach output of the previous unit is connected to the input of the following unit, and that’s why we see in the little table INPUT and OUTPUT designated pins. These units are chained and each have an input side and an output side.

strips can be sold as a white or a black strip (background strip).Not all strips of the same “model”, look the same, but have typically a very similar layout.Unlike the analog strips: Most Digital RGB strips operate on 5 Volts! In the illustration below you can see the physical differences between the WS2801 and the WS2811/WS2812 strips. The cool part of a digital strip is that you address each LED individually, making very cool effects easy. Obviously the kind we’d like to use in our projects. In particular: we will use the WS2812 in our project. The digital strips are the ones we will use in this project.

These spec sheets can also be downloaded with all 4 PDF’s bundled in a single ZIP file:Īnalog LED strips – Single color (top), Multicolor (bottom) DIGITAL RGB LED strips I have made the spec sheets of the 5050 LED, WS2801, WS2811 and WS2812 available as PDF: In my little Arduino project I’ll be using the WS2812. A Raspberry Pi typically runs Linux, which is not a so-called Real-time Operating System, where intended timing might be disrupted by other background activities. When using a Raspberry Pi however, using a WS2811/WS2812 can be a little bit more challenging due to the strict timing needs. Your selection here depends on what type of microcontroller you’ll be using and which of these are supported by the application or library you intend to use.įor example, Arduino based projects work fine with any of these, since everything runs real-time. The advantage of the WS2812 though, is that production of these combo’s in strips is easier and therefor cheaper, and each RGB LED takes much less space on strips. The WS2811/WS2812 depends on sending data matching a very tight timing. The WS2801 uses a separate clock line, which can be seen as an advantage, whereas the WS2811/WS2812 does not. Where the WS2801 strips needed 4 wires, the WS2811/WS2812 strips only needs 3 wires. Note how the layout of the “silver” tracks are almost identical in both images, yet the black (IC) block and the tiny wires are different (right).

On the left a 5050 RGB LED, on the right a WS2812 which combines a 5050 RGB LED with a WS2811 controller. In the illustration below you’ll see the difference: The 5050 LED is a very common 3 LED (Red, Green, Blue) package, in one 5mm x 5mm case.Ī WS2812 is the same package but with an additional WS2811 LED driver IC on board. The WS2812 however is a WS2811 placed inside a 5050 LED package. The WS2801 used to be quite popular but the WS2812/WS2811 appears to be taking over the reigns. Positioned close together, so you as a viewer will see the mixed color result. These IC’s can control up to 3 LEDs, typically Red, Green and Blue.

The WS2801 and WS2811 are LED driver IC’s ( Integrated Circuits). The model numbers WS2801, WS2811 and WS2812 actually refer to different “things”. Most projects and descriptions out there discus these sometimes mixed, and for one who dives into LED strips for the first time, these models numbers might be confusing. Difference between WS2801, WS2811 and WS2812īefore we start, we should probably identify the differences between the WS2801, WS2811 and WS2812 based strips (also called “strands”).
