What is WS2811?

The WS2811 is a three-output channel LED driver circuit. The WS2811 LED driver chip is widely used to control LED strips. WS2811 LED strip is usually 30 to 60 LEDs per meter. The voltage is 5V, 12V and 24V. Usually, 12V is more common.

5V, 12V and 24V WS2811 LED Strip

Figure 1 is a WS2811 LED strip with different voltages. WS2811 LED strip is an external IC. The WS2811 IC is mounted externally on the PCB. They are voltage compatible and have various cutting devices.

  • WS2811 5V LED Strip: Each LED can be cut and one WS2811 IC controls each LED.
  • WS2811 12V LED Strip: Three RGB lights can be cut and one WS2811 IC controls the brightness and color of these three lights at the same time.
  • WS2811 24V LED Strip: Six RGB LED lights can be cut and one WS2811 IC controls the brightness and color of these six lights at the same time.

Different Types of WS2811 LED Strip Products

Pros & Cons of WS2811

Given the wide range of applications for 12V WS2811, we will use a 12V WS2811 LED strip as an example to see the benefits and drawbacks of WS2811.

Pros of WS2811:

  • The 12V working voltage can control more LEDs in the strip.
  • Operating with a large number of LEDs is easy.
  • The 12V voltage allows for longer cable lengths.

Cons of WS2811:

  • The minimum control granularity is 3 LEDs because one IC controls 3 LEDs.
  • High power consumption due to operation under 12V voltage.
  • The 8-bit data limitation for each color results in a less smooth dimming curve.
  • No data redundancy available.

How to Use WS2811

WS2811 LED strip has three wires V+, Data and GND, as shown in the Figure 3.

Next let us understand how to control and connect the WS2811 LED strip.

How to Control WS2811 LED with Arduino?

Step 1. WS2811 includes an embedded version of WS2811 and three individually controlled LEDs, with an internal oscillator, signal reshaping, an amplification circuit, two digital ports, and an output drive.

Step 2. To control the LEDs, use “for loops” and libraries, with primary cases utilizing WS2812 LEDs, which have a high density, allowing for larger displays.

Step 3. For controlling a large number of LEDs, a LED driver is required, and a T300K controller is recommended for running video files through the LEDs.

Step 4. Ensure the interface is close to the LEDs, use a short data wire, and test with a proper 5V power supply with higher amps for longer life.

Step 5. Use high gauge wires to connect if the voltage is below 3V and avoid using the Z design as it causes serious data issues.

Step 6. Provide power to the LEDs with ones (1s) and zeros using binary representation, where each position in the binary representation has a weight from right to left with power 2 that increases gradually, as shown in Figure 5.

How to Program WS2811 through Adafruit?

Step 1. The WS2811 chip can drive a single normal anode RGB LED or three single-color LEDs, with each output having a constant current of ~18mA.

Step 2. The chip is chainable and requires a microcontroller, such as an AVR, Arduino, or PIC, as the protocol is sensitive to timing and can’t be used with a Linux-based microcomputer or a decoded microcontroller.

Step 3. The Neopixel library for Adafruit supports both speeds of the chip, and a 4MHz or faster processor is required for the slower timing rate.

Step 4. The WS2811 chip comes in a package of 10 individual chips, and Adafruit has an all-set component for it in its EAGLE library.

How to Control WS2811 LEDs with Raspberry Pi?

Step 1. Raspberry Pi can be used as a platform for controlling WS2811 LEDs for a light show, with a power cable that can handle the 10A required.

Step 2. After cutting the power cable, carefully connect VCC to V+ and GND to COM, and measure the voltage of the power supply with a multimeter.

Step 3. Raspberry Pi runs a custom Python sequencer program that takes inputs from an MP3 file and a sequence file to run the entire sequence.

Step 4. With the Raspberry Pi’s GPIO interface, 8 solid-state relays are used to control 8 series of lights, which are more than sufficient for a typical tree.
