Arduino - NeoPixel LED Strip Arduino - WS2812B LED Strip Arduino - DotStar LED Strip You have the flexibility to use either NeoPixel, WS2812B, or DotStar LED Strips. For the sake of simplicity in wiring, this tutorial specifically uses the DotStar LED Strip. Adapting the code for other ...
Neopixel是一种智能LED灯带,由Adafruit公司推出。它采用了WS2812B芯片,集成了控制电路和RGB LED,可以通过单一的数据线进行控制。Neopixel具有灵活性高、颜色丰富、亮度可调、可编程性强等特点,广泛应用于装饰灯光、艺术装置、电子制作等领域。 控制Neopixel灯带的方法是通过Arduino的GPIO口发送特定的数据信号。在Arduino中,...
// END of Trinket-specific code. pixels.begin();// INITIALIZE NeoPixel strip object (REQUIRED) } // 在这里编写你的代码,控制LED灯条的亮灭和颜色 voidloop() { pixels.clear();// Set all pixel colors to 'off' // The first NeoPixel in a strand is #0, second is 1, all the way up ...

void Adafruit_NeoPixel::clear(void)--用0填充整个像素条,即关闭所有WS2812灯珠。 void Adafruit_NeoPixel::Color(uint8_t r, uint8_t g, uint8_t b)--设置RGB的值,从0,0,0到 255,255,255。返回的是32位压缩RGB值,然后可以将其分配给a变量,供以后使用或传递给setPixelColor()函数。 void Adafruit_...
// On a Trinket or Gemma we suggest changing this to 1: #define LED_PIN 6 // How many NeoPixels are attached to the Arduino? #define LED_COUNT 60 // Declare our NeoPixel strip object: Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800); // Argument 1 = Number of...
电源 100个 WS2812b LED 的最大功率为 100x60mA = 6A。当然,如果降低亮度,功率损耗也会大大降低。5V 电源能够达到你想要的亮度。Arduino 该矩阵可直接在 Arduino 设备上使用 Adafruit 的 NeoPixel 库和NeoMatrix 库。如果你使用下面的用例,则必须修改 PIN 并初始化:NeoMatrix:...
