彩灯的多种玩法

此示例给出了控制彩灯的几种显示效果。 呼吸、流水、闪烁、彩虹、炫彩 硬件清单 mCookie-Battery mCookie-Core mCookie-Hub Sensor-Color_LED/zh 600px 电路搭建 将彩灯的IN接到Hub的6/7引脚，实际使用的是6号引脚。 将Battery、Core、Hub堆叠在一起，通过MicroUSB数据线接入电脑。 600px 代码 呼吸灯 #include <Microduino_ColorLED.h> //引用彩灯库 #define PIN 6 //彩灯引脚 #define NUMPIXELS 16 //级联彩灯数量 #define val_max 255 #define val_min 0 ColorLED strip = ColorLED(NUMPIXELS, PIN); //将ColorLED类命名为strip，并定义彩灯数量和彩灯引脚号 void setup() { strip.begin(); //彩灯初始化 strip.show(); } void loop() { rainbowCycle( 255, 0, 0, 5);//红色呼吸 rainbowCycle( 0, 255, 0, 5);//绿色呼吸 rainbowCycle( 0, 0, 255, 5);//蓝色呼吸 } void colorSet(uint32_t c) { for (uint16_t i = 0; i < strip.numPixels(); i++) { strip.setPixelColor(i, c); } strip.show(); } void rainbowCycle( int r, int g, int b, uint8_t wait) { for (int val = 0; val < 255; val++) { colorSet(strip.Color(map(val, val_min, val_max, 0, r), map(val, val_min, val_max, 0, g), map(val, val_min, val_max, 0, b))); delay(wait); } for (int val = 255; val >= 0; val--) { colorSet(strip.Color(map(val, val_min, val_max, 0, r), map(val, val_min, val_max, 0, g), map(val, val_min, val_max, 0, b))); delay(wait); } } 流水灯 #include <Microduino_ColorLED.h> //引用彩灯库 #define PIN 6 //彩灯引脚 #define NUMPIXELS 7 //级联彩灯数量 #define val_max 255 #define val_min 0 ColorLED strip = ColorLED(NUMPIXELS, PIN); //将ColorLED类命名为strip，并定义彩灯数量和彩灯引脚号 void setup() { strip.begin(); //彩灯初始化 strip.show(); } /*流水灯效果*/ void loop() { theaterChase(COLOR_RED, 2, 450); //红色流水灯效果，循环2次，两灯之间延时450ms theaterChase(COLOR_BLUE, 4, 400); //蓝色流水灯效果，循环4次，两灯之间延时400ms } //Theatre-style crawling lights. void theaterChase(uint32_t c, uint8_t n, uint8_t wait) { for (int j = 0; j < n; j++) { //do 10 cycles of chasing for (uint16_t i = 0; i < strip.numPixels(); i++) { strip.setPixelColor(i, c); //turn every third pixel on strip.show(); delay(wait); strip.setPixelColor(i, 0); //turn every third pixel on strip.show(); } } } 闪烁灯 #include <Microduino_ColorLED.h> //引用彩灯库 #define PIN 6 //彩灯引脚 #define NUMPIXELS 7 //级联彩灯数量 #define val_max 255 #define val_min 0 ColorLED strip = ColorLED(NUMPIXELS, PIN); //将ColorLED类命名为strip，并定义彩灯数量和彩灯引脚号 void setup() { strip.begin(); //彩灯初始化 strip.show(); } void loop() { ledBlinkALL(COLOR_BLUE, 1000); } //第n号灯，颜色c,闪烁时间wait void ledBlink(uint32_t c, uint8_t n, uint8_t wait) { strip.setPixelColor(n, c); //turn every third pixel on strip.show(); delay(wait); strip.setPixelColor(n, 0); //turn every third pixel on strip.show(); delay(wait); } //全部灯，颜色c,闪烁时间wait void ledBlinkALL(uint32_t c, uint8_t wait) { for (uint16_t i = 0; i < strip.numPixels(); i++) { strip.setPixelColor(i, c); strip.show(); } delay(wait); for (uint16_t i = 0; i < strip.numPixels(); i++) { strip.setPixelColor(i, 0); strip.show(); } delay(wait); } 彩虹灯 #include <Microduino_ColorLED.h> //引用彩灯库 #define PIN 6 //彩灯引脚 #define NUMPIXELS 7 //级联彩灯数量 #define val_max 255 #define val_min 0 ColorLED strip = ColorLED(NUMPIXELS, PIN); //将ColorLED类命名为strip，并定义彩灯数量和彩灯引脚号 void setup() { strip.begin(); //彩灯初始化 strip.show(); } /*彩虹灯效*/ void loop() { rainbow(20); } void rainbow(uint8_t wait) { uint16_t i, j; for(j=0; j<256; j++) { for(i=0; i<strip.numPixels(); i++) { strip.setPixelColor(i, Wheel((i+j) & 255)); } strip.show(); delay(wait); } } // Input a value 0 to 255 to get a color value. // The colours are a transition r - g - b - back to r. uint32_t Wheel(byte WheelPos) { WheelPos = 255 - WheelPos; if(WheelPos < 85) { return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3); } if(WheelPos < 170) { WheelPos -= 85; return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3); } WheelPos -= 170; return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0); } 炫彩灯 #include <Microduino_ColorLED.h> //引用彩灯库 #define PIN 6 //彩灯引脚 #define NUMPIXELS 7 //级联彩灯数量 #define val_max 255 #define val_min 0 ColorLED strip = ColorLED(NUMPIXELS, PIN); //将ColorLED类命名为strip，并定义彩灯数量和彩灯引脚号 void setup() { strip.begin(); //彩灯初始化 strip.show(); } /*炫彩灯效*/ void loop() { rainbowCycle(20); } // Slightly different, this makes the rainbow equally distributed throughout void rainbowCycle(uint8_t wait) { uint16_t i, j; for (j = 0; j < 256 * 5; j++) { // 5 cycles of all colors on wheel for (i = 0; i < strip.numPixels(); i++) { strip.setPixelColor(i, Wheel(((i * 256 / strip.numPixels()) + j) & 255)); } strip.show(); delay(wait); } } // Input a value 0 to 255 to get a color value. // The colours are a transition r - g - b - back to r. uint32_t Wheel(byte WheelPos) { WheelPos = 255 - WheelPos; if (WheelPos < 85) { return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3); } if (WheelPos < 170) { WheelPos -= 85; return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3); } WheelPos -= 170; return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0); } 相关案例 返回Sensor-ColorLED_Reference界面 返回Sensor-Color_LED界面
