What you’ll be taught
Utilizing HTTP request to load knowledge from public APIs
Utilizing JSON objects in Arduino
Displaying graphics and textual content on an OLED show
Mechanically match multiline textual content to a number of rows utilizing code
First expertise in Arduino improvement. You know the way to make use of the IDE and you may seek for/embody libraries.
On this video course you’ll learn to management a 0.96 inch OLED show with the U8g2 library. You may convert your personal JPG recordsdata into XBM recordsdata and show them on the show.
Within the subsequent part, we are going to fetch the present price/value knowledge of the specified cryptocurrencies by way of a free API. We’ll show these in EUR and USD on the show subsequent to a small graph. The API offers us with a timestamp, which we are able to use to show the precise date/time of the cryptocurrency’s value. This manner you might be at all times updated and hold an summary of your crypto portfolio.
Moreover, we may even show a multiline textual content, so that you could additionally use different APIs to your crypto ticker, resembling present information or climate knowledge.
On the finish of the coding I’ll present you the way to adapt the entire mission for the ESP8266. For this you want a barely totally different construction for the GET request. So you’ll be able to determine if you wish to use the ESP32 or ESP8266 for this mission.
In one other chapter, I’ll go into the development of the 3D printed case, in case you’re desirous about adapting or utilizing it. Within the final video I present you ways I assemble every little thing.
All codes will be downloaded, so you will get the consequence with out frustration.
We use the next elements on this sensible mission.
- OLED Show SSD1306 128×64
See you in school
