Grove - RGB LED Stick (10 - WS2813 Mini)

pir

We integrated 10 full-color RGB LEDs on this stick, with only one signal pin you can control all 10 LEDs easily. All the LEDs are WS2813 Mini, which is an intelligent control and high cost-effective LED. What's more, the WS2813 support signal break-point continuous transmission, which means you can continue to use other leds with one led be broken.

You can use this little stick create hundreds of thausands light effect, we hope it will bring you more fun.

Features​

  • WS2813B IC, 3535 LED
  • Intelligent Reverse-connection protection.
  • The gray levels of each pixel are of 256, which achieves “256256256=16777216” full-color display.
  • The refresh frequency reaches to 2KHz.
  • Serial cascade interface, data receiving and decoding depend on just one signal line.
  • Dual-signal wires version, signal break-point continuous transmission.

caution
The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

note
**1** Please plug the USB cable gently, otherwise you may damage the port. Please use the USB cable with 4 wires inside, the 2 wires cable can't transfer data. If you are not sure about the wire you have, you can click [here](https://www.seeedstudio.com/Micro-USB-Cable-48cm-p-1475.html) to buy

**2** Each Grove module comes with a Grove cable when you buy. In case you lose the Grove cable, you can click [here](https://www.seeedstudio.com/Grove-Universal-4-Pin-Buckled-20cm-Cable-%285-PCs-pack%29-p-936.html) to buy.
info
**1**. If the you uses Arduino UNO as the motherboard, it is recommended that use the DC power supply. Otherwise, the maximum ripple of VCC may exceed 100mV. If you use Seeeduino V4.2 as the motherboard, you do not need to connect DC power.

**2**. Hot swap is not supported.

  • Step 1. Connect the Grove - RGB LED Stick (10 WS2813 Mini) to port D6 of Grove-Base Shield.

  • Step 2. Plug Grove - Base Shield into Seeeduino.

  • Step 3. Connect Seeeduino to PC via a USB cable.

note
    If this is the first time you work with Arduino, we strongly recommend you to see [Getting Started with Arduino](https://wiki.seeedstudio.com/Getting_Started_with_Arduino/) before the start.

  • Step 1. Download the Led_Strip Library from Github.

  • Step 2. Refer to How to install library to install library for Arduino.

  • Step 3. Restart the Arduino IDE. Open the example, you can open it in the following three ways：

    1. Open it directly in the Arduino IDE via the path: File --> Examples --> Adafruit_Neopixel --> simple.

      pir

    2. Open it in your computer by click the simple.ino which you can find in the folder XXXX\Arduino\libraries\Seeed_Led_Strip-master\examples\simple, XXXX is the location you installed the Arduino IDE.

      pir

    3. Or, you can just click the icon

      pir

      in upper right corner of the code block to copy the following code into a new sketch in the Arduino IDE.

// NeoPixel Ring simple sketch (c) 2013 Shae Erisson
// released under the GPLv3 license to match the rest of the AdaFruit NeoPixel library

#include "Adafruit_NeoPixel.h"
#ifdef __AVR__
  #include <avr/power.h>
#endif

// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1
#define PIN            6

// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS      10

// When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals.
// Note that for older NeoPixel strips you might need to change the third parameter--see the strandtest
// example for more information on possible values.
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

int delayval = 500; // delay for half a second

void setup() {
  // This is for Trinket 5V 16MHz, you can remove these three lines if you are not using a Trinket
#if defined (__AVR_ATtiny85__)
  if (F_CPU == 16000000) clock_prescale_set(clock_div_1);
#endif
  // End of trinket special code
  pixels.setBrightness(255);
  pixels.begin(); // This initializes the NeoPixel library.
}

void loop() {

  // For a set of NeoPixels the first NeoPixel is 0, second is 1, all the way up to the count of pixels minus one.

  for(int i=0;i<NUMPIXELS;i++){

    // pixels.Color takes RGB values, from 0,0,0 up to 255,255,255
    pixels.setPixelColor(i, pixels.Color(0,150,0)); // Moderately bright green color.

    pixels.show(); // This sends the updated pixel color to the hardware.

    delay(delayval); // Delay for a period of time (in milliseconds).

  }
}
note
    The library file may be updated. This code may not be applicable to the updated library file, so we recommend that you use the first two methods.
  • Step 4. Upload the demo. If you do not know how to upload the code, please check How to upload code.
tip
    If every thing goes well, now you can see the LED strip shining:
