In this tutorial we will learn how to get the date and time from NIST TIME server using M5Stack Core ESP32 and Visuino, Watch the video! Step 1: What You Will Need M
本教程展示了如何构建一个 ESP32 Web 服务器,该服务器显示一个带有多个滑块的网页。滑块控制不同 PWM 通道的占空比,以控制多个 LED 的亮度。您可以使用此项目可以替换 LED 来控制需要 PWM 信号的直流电机或其它执行器。客户端和 ESP32 之间的通信是使用 WebSocket 协议完成的。此外,只要有变化,所有客户端都会同时...
