我们还使用了另一个流行的android应用程序“Blynk”来控制智能手机上的ESP32 GPIO。在硬件上做一些微小的改变,你可以用任何交流家用电器代替LED,通过互联网从任何地方远程控制它。 在之前的物联网文章中,我们使用ESP32使用IFTTT和Adafruit IO来控制LED。IFTTT和Adafruit IO是两个流行的云平台,可以轻松快速地构建基于物...
Equipped with a pre-built API, the EQSP32 simplifies device integration and ensures a smooth connection to various IoT platforms. Whether using Home Assistant, Node-RED, Dashio, Arduino Cloud, Blynk IoT or a custom solution, EQSP32 provides a reliable and scalable foundation for smart applicatio...
// Connect pin 1 (on the left) of the sensor to +5V // NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1 // to 3.3V instead of 5V! // Connect pin 2 of the sensor to whatever your DHTPIN is // Connect pin 4 (on the right) of the sensor to GROUN...

CORE1和CORE0上的LED愉快地闪烁,等待断开以重新连接。然而,如果!Blynk.connected(),核心0将尝试重新连接internet,在这种情况下,我的LED停止闪烁(应该继续闪烁,因为它在CORE1上运行。建立连接后,LED每300ms闪烁一次。看起来wm.autoConnect()功能不仅会阻止CORE0,还会阻止CORE1。
