Here’s a list of ESP8266 Tutorials you can try if you want to learn how to use this WiFi microcontroller. The ESP8266 and its compatibility with Arduino IDE paves the way for many WiFi-based projects. You can easily create web servers, IoT projects and many more!
Uploading sensor data to web servers is one of the core ideas for Internet of Things (IoT). Such data are often small-sized and are continuously updated over time. And while HTTP performs satisfactorily for simple applications, like how I showed in my NodeMCU web server tutorial, there is a need …
