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.
When I went to use esp12 and esp07, and the first problem was how to put it on the breadboard, luckily I found an adapter developed by tweeto, and that was what I needed, but I would like to make it easier to use, so I redesigned it smaller and added some labels to identify the pins, than I create a PCB to use It as programming board.
ESP8266, a little guide on how to use this low cost but powerful microcontroller with WIFI integrated.
Pinout, specifications and IDE configuration to start and programming your esp-12 and esp-07 variants.
esp-07 high resolution pinout and specs
esp-12 high resolution pinout and specs
WeMos D1 mini high resolution draw of pinout and specs
Notifications in all their forms and methods are fundamental, here is a tutorial on how to send emails and sms simultaneously with our nodemcu.
Here is a tutorial on Ebyte E22 LoRa (Long Range) library device very cheap and long-range (from 4Km to 10Km).

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.
