How to use The 64 LED 8x8 Grid NeoPixel

The 64 LED 8x8 Grid NeoPixel is a version of the NeoPixel series that includes 64 LEDs ni a 8x8 grid format. In this guide, we will be using the NeoPixel Compatible WS2812 5050 RGB LED (64 LED 8x8 Grid) from our store.

Parts

Wiring Guide

NeoPixel	Arduino
V+	5V
V-	GND
IN	Pin 6

Soldering is required to wire everything properly. Use jumper wires to connect the NeoPixel with the Arduino.

Programming

Step 1: Before we start coding, we first have to download the needed libraries.

Step 2: Enter NeoPixel and install the highlighted search.

Step 3: Declare your libraries

#include "Adafruit_NeoPixel.h"

Step 4: Declare an object using Adafruit_NeoPixel.

Adafruit_NeoPixel pixels(64, 6, NEO_GRB + NEO_KHZ800);

Adafruit_NeoPixel pixels(# of LEDS, digital pin #, LED type + LED type);

Step 5: Initialize the NeoPixel project.

void setup(){
    pixels.begin();
}

Now that everything has been initialized, you can code whatever you want.

Example

Here are a few commands you can use to control the NeoPixel:

object.setBrightness(0-255); //sets the brightness of the NeoPixels

object.clear(); //clears all the pixels

object.setPixelColor(pixel#, object.Color(R, G, B)); //sets a color for a specific pixel

The (R, G, B) can go from (0, 0, 0) to (255, 255, 255)

object.show(); //shows whatever pixel you have updated with setPixelColor

Here is an example of how to use the 64 LED 8x8 Grid NeoPixel.

Step 1: Initialize the NeoPixel.

#include "Adafruit_NeoPixel.h"
#ifdef __AVR__
    #include <avr/power.h> // this is required for 16 MHz Adafruit Trinket
#endif

int PIN = 6;
int NUMPIXELS = 64;

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup(){
    pixels.begin();
    pixels.setBrightness(10);
}

Step 2: Let's start by clearing the NeoPixel to make sure there is nothing on the LEDs.

void loop(){
    pixels.clear();
}

Step 3: Let's create a for loop that makes one LED light up after the other every second.

for(int i = NUMPIXELS; i >= 0; i--){
    pixels.setPixelColor(i, pixels.Color(255, i*3, 255)); //this should cause a white color to slowly turn into pink
    pixels.show();
    delay(20);
}

Full Code

#include "Adafruit_NeoPixel.h"
#ifdef __AVR__
    #include <avr/power.h> // this is required for 16 MHz Adafruit Trinket
#endif

int PIN = 6;
int NUMPIXELS = 64;

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup(){
    pixels.begin();
    pixels.setBrightness(10); //to not ruin my eyes
}

void loop(){
    pixels.clear();
    for(int i = NUMPIXELS; i >= 0; i--){
        pixels.setPixelColor(i, pixels.Color(255, i*3, 255)); //this should cause a white color to slowly turn into pink
        pixels.show();
        delay(20);
    }
