PWM
PWM调光
1、学习目的：利用定时器产生PWM，了解原理和使用方法
2、硬件要求：LED灯 定时器
3、试验现象：LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象(PWM dimming, learning objectives: the use of the timer to generate PWM understand the principles and use hardware requirements: LED lamp timer test phenomenon: LED lights from bright to off, gradually changes from off to bright, that is, adjusted optical phenomena)
