本项目将在Arduino IDE环境下，利用ESP32产生的PWM信号控制多个LED。项目所需物料如下： ESP32带一个包含16通道LED PWM控制器，可配置以产生不同特性的PWM信号。项目开始之前需要先安装Arduino IDE，连接妥当后就可以把ESP32 DOIT DEVKIT V1板用作LED PWM控制器了。 使用Arduino ...

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。 电路图使用AD21 ...

PegorK's f32 might be the world's smallest ESP32-C3 board. It measures just 9.85 x 8.45 mm, or slightly larger than the area covered by a USB Type-C ...
