This project brings support for the ESP8266 chip to the Arduino environment. It lets you write sketches, using familiar Arduino functions and libraries, and run them directly on ESP8266, with no external microcontroller required. ESP8266 Arduino core comes with libraries to communicate over WiFi us...
With MicroPython you can write clean and simple Python code to control hardware instead of having to use complex low-level languages like C or C++ (what Arduino uses for programming). Its great for... Add to Cart, Python for Microcontrollers: Getting Started with MicroPython $24.95 24 ...

在前面的博文中,博哥介绍了 PubSubClient 这个使用率很高的Arduino MQTT库,具体可以参考 玩转PubSubClient MQTT库。 然而,博哥这里重点讲解另一款使用率也非常高的Arduino MQTT库 —— Adafruit_MQTT。 当然,博哥这里不会重点讲解MQTT协议(毕竟以前的博文已经花了很大篇幅讲解),需要了解的同学请仔细阅读 玩转PubSub...

The objective of this post is to explain how to create a simple websocket client on the ESP32, using the Arduino core. The tests of this ESP32 tutorial were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. Introduction The objective of this post ...
