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 ...

Over the years we’ve seen countless ways of displaying the current time, and judging by how many new clock projects that hit the tip line, it seems as though there’s no end in sight. Not that we’re ...

Convenience has always been the driving force of human ingenuity. From its simplest forms such as hand tools, wheels, and inclined planes, technology has allowed humans to live more comfortably. Most ...
