In the previous article, we found that our HTTP server cannot handle hypertext that points to a nonexistent page. We've found that the browser will also request favicon.ico for each page.
In the previous example, we created an HTTP server with three pages. If you look at the source code of the server, you will find the html directory where are the source codes of HTML pages. In this directory I created the design of each page.
In this article, we'll build on the articles we learned to create a simple page and give it a nice responsive design. We will now try to create an HTTP server that contains multiple pages. You will be able to switch between pages using hypertext.
In the previous article, we created an HTTP server with one page. Pages are formatted with HTML tags. Use these tags to design a basic page structure that looks amateurish.
Node-RED can work with serial port. In this article, we will connect the Arduino and the DS18B20 temperature sensor to the serial port. Arduino will send the measurement results through the serial port, and Node-RED will parse them to make it easier to process.
This article will show you how to create flows. It will be a simple example based on an example from the official documentation. The generated flow will have one input, one function that modifies the data and one output on the debug console.
Node-RED is a flow-based environment that lets you create data flows. It works as a package for Node.js that installs on your computer.
In this article we will program the HTTP server using the ESP8266 microcontroller. It will be a simple HTTP server that provides one page. In the example, we'll show you how to program this server.
Large companies promise a great future from IoT, and Arduino is not out of the question. In recent months, we've noticed that both Arduino Cloud and Google Cloud have gone from beta to more complete versions. I do not follow Amazon and Microsoft but they also work intensively on IoT.
The ESP8266 microcontroller allows you to store data using the SPIFFS file system. The data is stored in internal Flash memory. Flash memory is divided into several blocks.
In today's article, I would like to start working on a simple thermometer theme, which I will gradually improve. In the first article we create a simple thermometer with the ESP8266 microcontroller and the DS18B20 integrated circuit. The result will be displayed on the OLED display.
In this article we will describe the project of a miniature thermometer. We will use the ATtiny85 microcontroller and the DS18B20 integrated circuit. The result will be displayed on the TM1637 display.
In 2019, we continue the course. The form of the articles on the blog has settled in the way it suits me. I have set a reasonable compromise between the needs of our children and the pursuit of free time in electronics.
