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。 通过设置正确的信号属性，这种方法可用来控制其他PWM输出，如马达、LED 呼吸灯等。

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。

Last year we built a drone using ESP32 and our community loved it. Since then the project has evolved and the drone is now ...

While they differ a lot in terms of functionality, you can combine the IoT-centric ESP32 boards with the all-powerful Raspberry Pi SBC family to build some truly remarkable DIY projects.

We’ve seen a lot of ESP32 projects here at Hackaday, including this most interesting clock. Be sure to check out the video below to see the smart lights in action.

Internally the device is very simple, with the 5 mm LEDs and their associated resistors connected directly to the digital out pins on an ESP32 development board.
