任务3：控制WS2812B

    事实上，这个任务还是调库，什么？你说你想做点有创意的动画效果？不好意思，常见的LED动画效果也已经有库可以使用了（有一说一，Python太方便了）。找到adafruit_led_animation库文件夹，其中的animation文件夹包含了好几种动画效果，你可以选择一个LED灯条，也可以直接使用这个板子自带的neopixel，我这里选择并调用的是blink（闪烁）和colorcycle（色彩循环）两种动画效果，为了省事，colorcycle直接带有‘rainbow’的循环模式，连颜色都不用自己选了。可以设置动画速度（说起来是speed，其实是一个动画的周期，单位是秒）、亮度等等。

    为了控制LED，还需要按键，我这里使用的是自带的boot按键，RST是复位按键，不能当普通按键使用。按键控制的电平通过io口读取，所以要调用digitalio库，使用DigitalInOut(board.BOOT0)获得boot按键对应io口的实例，并用direction属性控制输入（Direction.INPUT）或是输出，用pull属性设置输入模式是上拉（Pull.UP）或下拉（Pull.DOWN），IO口输入的电平值可以使用buttom.value来获取。

    以下是我的代码，三种显示模式：翡翠色快闪，蕾丝白慢闪和彩虹色循环，按一次键变一次。
