WS2812B Smart RGB Led Light Strip Black/White

$8.95$57.95
256 brightness display and 24-bit color display. Each pixel can have its own color and brightness. You can control them individually and set them to any color or animation you want. It can be programmed with Arduino, FastLED library, Raspberry Pi, Fadecandy, T1000S etc. It can also be controlled by SP105E, SP103E, HC008 and other pre-programmed WS2811 controllers. Covered with silicone weatherproof sheathing, which protects it very well and makes it easy to clean. It comes with clips and screws and can be installed easily. Come with 3pin JST-SM connectors and separated power/ground wires on both ends. Each LED can be cut off without damaging the rest strip. You can shorten, lengthen or bend it freely if you want. Used to make led screen, led wall, advertising board and widely applied to hotel, KTV, bars, Outdoor advertising signs, Christmas or wedding party decoration, and so on.

WS2812B is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent.

The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel,the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission

LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angl e is large, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation

What’s great about these LEDs is that we can control even the entire LED strip with just a single pin from our Arduino board. Each LED has three connectors at each end, two for the powering and one for the data. The arrow indicates the data flow direction. The data output pad of the previous LED is connected to the Data Input pad of the next LED. We can cut the strip to any size we want, as well as distance the LEDs using some wires.

As for the powering they work on 5V and each Red, Green and Blue LED draws around 20mA, or that’s total of 60mA for each LED at full brightness. Note that when the Arduino is powered via the USB, the 5V pin can handle only around 400 mA, and when powered using the barrel power connector, the 5V pin can handle around 900 mA. So if you are using more LEDs and the amount of current that they would draw exceeds the limits mentions above, you must use a separate 5V power supply. In such a case you also need to connect the two Ground lines two each other. Additionally it is recommended to use a resistor of around 330 Ohms between the Arduino and the LED strip data pin in order to reduce the noise on that line, as well as a capacitor of around 100uF across the 5V and Ground to smooth out the power supply.
