由于所有GPIOs 输出了相同PWM信号，所有三个LED亮度的增加与减少是同时进行的，这样就产生了一个非常美妙的同步效果。 本项目演示了如何在Arduino IDE环境下，使用ESP32的LED PWM控制器进行调光控制。

本项目是Fastbond智能建筑项目，使用了ESP32作为物联主控，驱动墨水屏，使用PWM信号驱动美信MAX16820芯片控制宿舍灯光的亮暗变化，同时设计了基于ADI公司LTC4054芯片的锂电池充电管理电路，可以在没有外部供电的情况下，进行墨水屏刷新的操作。

To achieve this he created Fade, a custom programming language/framework for controlling LED animations from the ESP32. Fade is written for addressable RGB LEDs like the Neopixel/WS2812.

Not that we’re complaining, of course. The latest entry into the pantheon of unusual timepieces is this ESP32-powered desk clock from [Alejandro Wurts] that features a folding LED matrix display.
