Bluno控制灯带

最近到手一套蓝牙炫彩LED灯带套件，听起来就酷的不行。。。正直双蛋期间，可是我木有圣诞树做装饰，暂且只能玩玩灯带，还望各位看官忍受一下
1、套件清单

[*]BLUNO控制器    1个
[*]模拟声音传感器 1个
[*]音频分析模块    1个
[*]3米WS2812灯带    1条
[*]传感器扩展板V7 1个
[*]电源转接头       1个
[*]5V@3.6A电源适配器1个

2、连接

Bluno和扩展板连接

电源转接头连接

传感器连接

整体连接起来

3、编程控制（用的官网代码示例）
{:5_168:}

first sample，不用蓝牙模块，也不需要传感器，效果如下图

代码
/*
This code can be a good test code for your strip
function: leds.setPixelColor(i,y) can be used to let number i of your led turn on with color of y
and you can draw your idea easily with this function but never forget function: led.show()
*/

#include <Adafruit_NeoPixel.h>

#define PIN 6 //The signal pin connected with Arduino
#define LED_COUNT 180 // the amount of the leds of your strip

// Create an instance of the Adafruit_NeoPixel class called "leds".
// That'll be what we refer to from here on...
Adafruit_NeoPixel leds = Adafruit_NeoPixel(LED_COUNT, PIN, NEO_GRB + NEO_KHZ800);

void setup()
{
leds.begin();// Call this to start up the LED strip.
clearLEDs(); // This function, defined below, turns all LEDs off...
leds.show(); // ...but the LEDs don't actually update until you call this.
}

void loop()
{
for (int i=0; i<LED_COUNT; i++)
{
rainbow(i);
delay(50);// Delay between rainbow slides
}
}

// Sets all LEDs to off, but DOES NOT update the display;
// call leds.show() to actually turn them off after this.
void clearLEDs()
{
for (int i=0; i<LED_COUNT; i++)
{
leds.setPixelColor(i, 0);
}
}

// Prints a rainbow on the ENTIRE LED strip.
//The rainbow begins at a specified position.
// ROY G BIV!
void rainbow(byte startPosition)
{
// Need to scale our rainbow. We want a variety of colors, even if there
// are just 10 or so pixels.
int rainbowScale = 192 / LED_COUNT;

// Next we setup each pixel with the right color
for (int i=0; i<LED_COUNT; i++)
{
// There are 192 total colors we can get out of the rainbowOrder function.
// It'll return a color between red->orange->green->...->violet for 0-191.
leds.setPixelColor(i, rainbowOrder((rainbowScale * (i + startPosition)) % 192));
}
// Finally, actually turn the LEDs on:
leds.show();
}

// Input a value 0 to 191 to get a color value.
// The colors are a transition red->yellow->green->aqua->blue->fuchsia->red...
//Adapted from Wheel function in the Adafruit_NeoPixel library example sketch
uint32_t rainbowOrder(byte position)
{
// 6 total zones of color change:
if (position < 31)// Red -> Yellow (Red = FF, blue = 0, green goes 00-FF)
{
return leds.Color(0xFF, position * 8, 0);
}
else if (position < 63)// Yellow -> Green (Green = FF, blue = 0, red goes FF->00)
{
position -= 31;
return leds.Color(0xFF - position * 8, 0xFF, 0);
}
else if (position < 95)// Green->Aqua (Green = FF, red = 0, blue goes 00->FF)
{
position -= 63;
return leds.Color(0, 0xFF, position * 8);
}

return leds.Color(0, 0xFF - position * 8, 0xFF);
}
else if (position < 159)// Blue->Fuchsia (Blue = FF, green = 0, red goes 00->FF)
{
position -= 127;
return leds.Color(position * 8, 0, 0xFF);
}
else//160 <position< 191 Fuchsia->Red (Red = FF, green = 0, blue goes FF->00)
{
position -= 159;
return leds.Color(0xFF, 0x00, 0xFF - position * 8);
}
}
second sample，Bluno蓝牙控制，嘎嘎
这个是可以通过手机app来控制的，当手机与Bluno蓝牙配对连接后就可以控制了，app的下载网址https://www.dfrobot.com.cn/goods-823.html

}另外，上面这段程序如果不连接蓝牙的话，则是声音传感器和音频分析模块来通过分析外界声音，使灯带有节奏的变化
