Blog for fans of Arduino and electronics.
Arduino is an open-source platform based on Atmel microcontrollers and a graphical development environment. The Arduino board is designed to be used immediately for experiments. Just plug it into a USB, install the development environment and start programming.
If you are here for the first time, start a short tour of this site.
Recent changes on the site.
ESP8266 je lacný čip s podporou Wi-Fi. Výrobcom čipu je spoločnosť Espressif Systems.
Korg Volca je séria syntetizátorov od firmy Korg. Zaradil som ju sem preto, lebo každý syntetizátor má MIDI vstup a chcel by som napísať niekoľko článkov o ovládaní MIDI pomocou Arduina.
DS18B20 je digitálny senzor teploty s rozlíšením 9-12 bitov. Komunikuje pomocou rozhrania One Wire.
Toto je stránka, ktorá slúži ako rozcestník na experimenty s menšou verziou Arduina. ATtiny85 má 8 kB flash pamäte, 512 SRAM a 512 EEPROM.
Analógovo-digitálny prevodník vykonáva prepojenie medzi analógovým a digitálnym svetom v Arduine. Okolité prostredie často poskytuje analógový signál, ktorý ale nevieme priamo spracovať.
List of current articles.
The ESP8266 microcontroller allows you to store data using the SPIFFS file system. The data is stored in internal Flash memory.
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.
In this article we will describe the project of a miniature thermometer. We will use the ATtiny85 microcontroller and the DS18B20 integrated circuit.
In 2019, we continue the course. The form of the articles on the blog has settled in the way it suits me.
The integrated circuit DS18B20 (1-Wire digital thermometer) can be connected in two ways. In normal wiring, pin 3 connects the VCC and the circuit is powered from there.
You can find basic information about Arduino on the site. You can use the quick index of root pages at the top of this page. Or use a full index of pages where there are all pages of the site. You can also track progressive changes in the site history.
The second part of the site is a blog. There are sequentially written blogs that are sorted by time. The page is usually the starting point of the topic, and there are more articles in the blog that describe the topic.
The third part of the site is a list of downloads. It contains libraries, datasheets, and programs for Arduino. All programs for Arduino are also available on GitHub.
The fourth part consists of applications. You will find there several applications that interactively calculate the results from the entered values. For example, there is Arduino Timer Calculator.
The fifth part is a list of microcontrollers from Atmel.
The last part of the site is a list of videos that are complementary to the site or the blog information.
Here's the information I've learned about Arduino. The Arduino fans community has a good habit of sharing all the knowledge, and everyone has access to the source texts of the programs as well. This is the second version of the page. I originally used Google Sites where I wrote notes. It took about a year and I have no reason to conceal that at the time I did not know anything about electronics. But by using Arduino, I quickly penetrated the secrets of electronics. I found quite helpful my extensive experience with programming in C++, so I was able to throw myself straight into the creation of programs.
Gradually, the volume of data has increased and Google Sites were not enough. So I switched to Google App Engine and in Python I programmed these pages. Google App Engine, on the one hand, is a robust system running on the same infrastructure as Google itself. On the other hand, this is a relatively novel system, where a lot of common things are not available. But programming itself in it is very easy and, compared to PHP, you will wonder at the possibilities there are here.
The following pages are related to this one.
I try to make the content of the site so that it can be easily displayed on both the desktope and the mobile phone. This is working quite well. I also work on translating these pages into English and Czech. I'm using the Cloud Translation API. Neural network translations are improving every day, allowing allowing us to leave translation to artificial intelligence. Some mistakes may appear in the translations, but this should not prevent a comfortable reading of these pages in your native language.
