What Is An Addressable LED Strip, and How Do I Use It?

Table of Contents

First and foremost, I’m afraid I won’t be able to answer your question about the “best” LED strip. The truth is that there are various factors to consider, and each application will almost certainly necessitate a specific style of the strip. This article’s goal is to assist you in determining which type of individually addressable LED is suitable for your project based on a variety of variables.

Without a question, addressable LED strips are the most dynamic LED strip lighting choice. They have a one-of-a-kind architecture that allows you to control individual LEDs or specific LED channels to create a wide range of effects. Multiple effects can be customized in terms of color, brightness, and timing.

As a result, the question of how to control the addressable LED strips to generate this dynamic effect arises. Is it possible to get addressable LED controllers? How do they function?

Let’s have a look at some of the most important issues.

What is an addressable LED strip 


When you require a dynamic lighting solution, LED strips are the way to go. They come in a variety of colors, can be mounted practically anyplace, and require little to no upkeep. You’ll be hard-pressed to find a lighting system with as much value and style as this one.

Addressable LED strips, on the other hand, raise the bar significantly. They provide you with additional control and distinctive effects, allowing you to improve your lighting setup even more. The catch is that you must select the appropriate sort of addressable LED strip for your needs.

A built-in driver is included in each addressable LED in a programmable LED strip, allowing the brightness and color of each RESULTED IN to be adjusted independently. That is, each LED can have a different hue than the one adjacent to it. This enables you to apply various effects to different portions of the LED strip at the same time or at different intervals. It’s perfect for displaying animations and other dynamic displays, as well as creating stunning lighting effects.

Individually addressable RGB LED strips to come in 5V and 12V versions, each with its unique set of benefits. Because 12V LED strips are less subject to voltage loss, they may travel further distances before the LEDs fade and turn an erroneous hue. If you plan to run your strip for any length of time, you should inject power at both ends and probably somewhere in the middle. You’re utilizing a 5V battery. The benefit of using a 5-volt power board is that you can supply the NodeMCU with the same power without the requirement for a voltage regulator.

LED strips that can be individually addressed come in a number of styles.

The SK6812 is a single-wire interface chipset for SMD5050 and 8-12mm through-hole LEDs. It is usually the cheapest choice, although data and PWM rates are slower. There are several variants available, all of which use the same protocol.

The WS2812 looks a lot like the SK6812.

APA107: Our current “new kid on the block” is the APA107. This chipset is embedded into the SMD5050 LED, just as the WS2812, except it uses a 2-wire interface and can achieve PWM speeds of up to 30Mbps and 9kHz. The design is unique to Nova.

HD107s: An improved APA107 with a +26kHz PWM refresh rate.

6-pin SMD5050 package version SK6813/WS2813 (original SK6812 was 6-pin).

The WS2815 is a digital LED light source that is placed in an SMD 5050 kit and has an RGB chip and power circuit control.

WS2801: The WS2801 is a mid-priced two-wire panel with an eight-color output channel that requires a total of 1 Mbps of data.

WS2811: This is a bare IC type that is commonly used in Christmas lights and 12V strips (3 RGB LEDs per IC)

WS2811 400kHz: The chipset’s first version runs at 400kHz, with the following versions running at 800kHz. LED TYPE.WS2811 400 is required for this model. These are becoming harder to come by.

LPD8806: An outdated but still available chipset with a 2-wire interface and high PWM speeds that can support 20Mbps. The disadvantage is that each IC controls two LEDs, and each channel only has seven bits rather than eight, thus it can only handle one-eighth of the color.

What Is an Addressable LED Strip and How Does It Work?


The addressable LED strip’s operation necessitates the cooperation of various components. The following are the details.

IC (integrated circuit)

Light-emitting diodes (LEDs) are a type of power source.

A controller that is wireless

Each LED has an integrated circuit chip of its own. This is the system that allows you to individually control LEDs. The controllers used to control them are likewise unique; instead of matching RGB pins like a standard RGB LED strip, they include data channels for sending commands.

In light of this, the addressable LED strips work as follows:

DC power is applied to the LEDs when the power is turned on, causing them to light up in their default configuration.

You’ll utilize the controller to give a command to the individual LED you to wish to control to produce the effect.

After that, the controller sends a signal to the LED’s IC chip.

When you enter a lighting effect at a predetermined interval, the circuit chip either executes the instruction right away or saves it for later.

What are the components you’ll need to get ready?


You will require the following items.

A computer that can run the Arduino IDE, such as a PC, laptop, MAC, or another computer.

The FastLED IDE library is a clone of the original.

a computer processor (we recommend UNO R3 or Pro Micro)

RGB party lights or WS2811 LEDs, addressable LED strips of the required length.

A power supply with a 5-volt output is available (VUPN7753)

Adapter from one screw terminal to a DC barrel connector (optional) CD021

Several cables for connecting the Arduino’s data and power (I use male to male jumpers)

The Arduino is programmed

Programming Arduino

It’s simple to connect to Arduino. From here on out, we’ll be talking about the Arduino Uno R3 or its R3 counterpart.

A 5 volt supply power is required for the LED strips. The LED strips must be connected to both POSITIVE and NEGATIVE.

Connect the power supply’s positive and negative 5-volt terminals to the Arduino, and the positive 5 volt terminal to the Arduino’s “5V” connector. Connect the negative 5V terminal to the Arduino’s “GND” connector, which is next to the “5V” connector.

Finally, connect the “Din” on the LED strip to the Arduino plug’s “12” pin. (Alternatively, any of the data pins listed in your FastLED software can be used.) I only utilized pin 12 for my project).

Arduino is a free and open-source platform for electrical prototyping. It consists of a physical circuit board and software for programming the physical board that can be run on a computer. It can be used as an addressable LED lightbar controller due to its programmability. However, before you utilize Arduino as a control device, make sure your addressable LED strip is suitable.

To use Arduino to control an addressable LED strip, you must first install the library. The library is a cryptographic system that uses Arduino commands to send signals to an addressable strip. There are a number of libraries to pick from, with some of them even being free. The key distinction is that some LED strips are more compatible than others with a large number of addressable LED strips.

To get the FastLED library installed.

1)The FastLED library can be downloaded by clicking here. There should be an a.zip folder in your download area.

2)To acquire the FastLED-master folder, unzip the.zip archive.

3)It’s time to rebrand FastLED-master to FastLED.

4)Place the FastLED folder in the Arduino IDE installation’s libraries folder.

5)Finally, the Arduino IDE should be restarted.

The majority of libraries come in ZIP format. Unzip your library and place it in the Arduino libraries folder to begin using it. You must first specify the parameters for the LED strip settings before you can begin inputting commands into the application. This definition allows you to choose which LED channels to control.

Upload the following code to your Arduino board after installing the appropriate libraries. Copy the code below or go to File > Examples > FastLED > ColorPalette in File > Examples > FastLED > ColorPalette.

The NUM LEDS variable must be changed to reflect the number of LEDs in the bespoke LED strip. In our situation, the LED strip is 14 LEDs long.

Adjust the LED PIN variable if you want to control the LED strip with another Arduino pin.

LED controller with wireless addressability

wireless addressable led controllers

Our Dream color LED controller, which enables WIFI and Bluetooth APP/Amazon/Google/RF control with various control technologies such as timer/music/group features, is used to control almost all addressable LED strips.

Home lighting that is tailored to each individual (one LED controller controls one LED strip) For clients operating programmable systems within the system, this can be accomplished via Arduino panels, where the drive system and database form the data flow that defines how the LED strips function.

SD digital LED controllers (T-1000S/K-1000C/T-4000/K-8000/T-300K) programmed online/offline to output LED display light effects from one to many (one LED controller controlling numerous LED strips).

One-to-many industrial lighting with DMX signal converter support Art-net SPI LED strip display lighting effects for each output channel through PC Mardix or addressable LED strip display lighting effects for different positions of DMX SPI decoder (DSA / LT-DMX-1809) via DMX console is controlled by DMX digital LED controllers (BC-204 / BC-216).


If you thought wirelessly controlled RGB LED strips were the peak of LED lighting innovation, addressable LED strips will completely change your mind. They are unrivaled in terms of inventive possibilities. With all of the information you’ve gathered, all that’s left is to select a reputable addressable LED strip manufacturer to help you bring your lighting project to life.
