Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
In this article we will transform our ESP into a generic Web Server capable of deploying an entire website.
Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
When we speak about web server we know that the basic is serving a web page, in a micro-controller we have some solution to do that.
Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
Now we are going to learn the basics, and a simple sketch to manage builtin led.
One most common need when you use IOT device with WIFI is the first connection attemp, It’s very tedious to hard code WIFI parameter, but a library allows you to connect your esp8266/esp32 to different Access Points (AP) without having to hard code and upload new code to your board. Additionally, you can also add custom parameters (variables) and manage multiple SSID connections with the WiFiManager library.
Here is a tutorial on Ebyte E22 LoRa (Long Range) library device very cheap and long-range (from 4Km to 10Km).
Start with specs and basic use.
ESP32 have 2 multiple UART, they are very usefully for debug, and this device have also a core logging system that you can use to debug and control your code.
I would like to monitor the status of my ABB Aurora inverter (formerly Power One now Fimer). So with a WeMos D1 mini I create a monitoring station with web interface, notifications and more.
Now we are going to wire our Arduino to the Inverter.
Here my library that implements the complete communication protocol of ABB (ex PowerOne) Aurora Inverter suitable with Arduino, esp8266 and esp32.
When you create a device you probably need to know the correct time, on wifi device the resonably choiche is to use Internet to get time via NTP.
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. CORS request, OPTION and POST.
