Once the hardware part is done you need to upload the code to control the circuit. You can find the sketch in myArduinoPomodoroTimer github repo. The most complicated part of the code is setting up the interrupt handler. I took it from my other project where I built a digital clock usin...

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_...

Arduino设备的引脚有数字量(Digital)I/O引脚、模拟量(Analog)输入引脚、模拟量输出引脚(PWM脉冲宽度调制)、电源引脚(GND/5V/Vin)、串口引脚(TX/RX)、外部中断、SPI等,详情可查阅这里,对于不同的开发版引脚都是大同小异,查阅引脚说明即可。 // 循环亮灯// 5 ---> + --// |// LED// |// GND --->...
