是否可以通过Arduino并行制作多个NEOPIXEL条纹的动画?
Is it possible to animate multiple NEOPIXEL stripes in parallel via Arduino?
问:
我正在为我的一个好朋友做一个正在进行的项目。我对这个编程的东西很陌生,所以我被迫寻求帮助。
他想用一些LED条纹来显示点亮效果。这是棘手的部分。他已经买了 4 个 24V 条纹,但就我而言,这些应该适用于该项目。我已经掌握了一段非常漂亮的代码,它类似于这个项目所需的大多数属性,但它也缺少一些东西,而且我太缺乏经验,无法自己处理它。
首先,他希望条纹一个接一个地动画化,但没有任何明显的顺序。我本来想投入一些RNG来做这项工作,但我惨遭失败。除了杀死整个代码之外,没有太多的选择,我真的不太了解它。所以这部分也是没问题的。
动画本身很棒,我真的很喜欢它。唯一让我感到不安的是那里只使用了 3 种颜色的限制。它们也遵循相同的顺序,我还没有找到一种方法来随机化它们
如果有人能帮我解决这个问题,我会非常高兴。
这是代码,如果有人需要它。
