笔记 一个按键控制的 10 级变速跑马灯试验
在本课中，我们要用一个按键来实现跑马灯的 10 级调速。这又会涉及到键的去抖的问
题。&nbsp;
本课的试验结果是，每按一次按键，跑马速度就降低一级，共 10 级。&nbsp;
这里我们又增加了一个变量 speedlever，来保存当前的速度档次。&nbsp;
在按键里的处理中，多了当前档次的延时值的设置。&nbsp;
请看程序：&nbsp;

笔记 模拟 PWM 输出控制灯的 10 个亮度级别
LED 一般是恒流操作的，如何改变 LED 的亮度呢？答案就是 PWM 控制。在一定的
频率的方波中，调整高电平和低电平的占空比，即可实现。比如我们用低电平点亮一个 LED
灯，我们假设把一个频率周期分为 10 个时间等份，如果方波中的高低电平占空比是 9：1，
这是就是一个比较暗的亮度，如果方波中高低电平占空比是 10：0，这时 ...
