SSD1306 IC is used for the most commons OLED display is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons.
We will now render images and create a simple animation and take a look at the byte array generator.

We are going to use it with SPI and i2c and learn the basic function.
Here is a tutorial on Ebyte E22 LoRa (Long Range) library device very cheap and long-range (from 4Km to 10Km).
Library specification
Modern web application need realtime update, for year we use polling system with REST call but now we can’t ignore WebSocket.
Here a complete reference implementation of a web application with token authentication.
Modern web application need realtime update, for year we use polling system with REST call but now we can’t ignore WebSocket.
Here a WebSocket server with esp8266, esp32 with some method to enable authentication.
Modern web applications need to update data in real time, for years we have used polling with REST calls but now we can no longer ignore the WebSocket protocol.
Here I am going to present a WebSocket client with esp8266, esp32 and Arduino Mega with enc28j60.Here a WebSocket client with esp8266, esp32 and Arduino Mega and enc28j60.

Start with specs and basic use.
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.
Where are we store the data and html page?? In this article the solution.

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.
