In a previous tutorial we already saw how to control a WS2801 RGB LED strip.
WS2801 on a Raspberry Pi With only one data line, the frequency must be higher to carry the same amount of data. In terms of price, however, they are still cheaper than a similarly long WS2801 strip with only 32 LEDs These have a higher density of lights and thus a higher brightness. My recommendation is the middle version with 60 LEDs/m. The length should be chosen depending on the project to be implemented. These are available in three different versions, which differ in the number of LEDs per meter: In addition, of course, the actual RGB LED strip of the type WS2812 (B) or WS2811 (also called NeoPixel) is required. If you have more LEDs in use, you may need more than one power supply (more on that later). So, a power supply, which has up to 10A is suitable. According to the data sheet, an LED under full load (= maximum brightness) needs about 60mA. The maximum power of the power supply depends on the number of LEDs. For experienced: switching power supply 5V 10A + power cord.For beginners: power supply + connector (see picture right).This includes the following in addition to a Raspberry Pi: This has – apart from the price – a few advantages, which will be discussed in more detail below.Ĭomponents A plug adapter makes connecting the power cable to the power supply very easy.Īnyone who has already used an RGB LED strip (such as Ambilight) can continue to use the accessories. It must be said that one should not be fooled by the “smaller” model number of the WS2801. The models WS2812B and WS2811 are also compatible and can be addressed with this guide. After using the latter in a previous tutorial and using it in our Ambilight, this tutorial is about using the Raspberry Pi WS2812 RGB LED Strip. These two LED strips are very different, but both can be controlled with the Raspberry Pi. If you are looking for RGB LED strips, you will probably come across the WS2812 or the WS2801.
