![]() ![]() Both of them are designed for the ESP family. Personally, I will prefer the library among the first two on the list. You can open library manager from Sketch -> Include Library -> Manage Libraries. The best and easiest way to install these libraries is from Arduino IDE’s library manager. ![]() For the Arduino family, you can use this GitHub library and for ESP8266, NodeMCU or ESP32 you can use this GitHub library. It again depends on the development board you are using. The very first basic step will be installing libraries required for QR Code generation. Installing the necessary libraries for QR code generation on Arduino or ESP Now, let’s start with the installation of the required libraries. If you want to know, how to interface OLED display with NodeMCU, you can check out this post. If you are new to program ESP8266 or NodeMCU, use this guide to program ESP8266 or NodeMCU using Arduino IDE. This tutorial will be useful for Arduino and NodeMCU or ESP8266. In this tutorial, we will study how to show QR code on an OLED display using Arduino or ESP8266. ![]() We can share such data without any actual communication between two devices or one device and paper. Here, different forms refer to any kind of text, contact number, identification number, or URL. QR code gives us easy accessibility for the sharing of a few bits of data in different forms. Nowadays, almost every smartphone comes with a pre-installed QR code scanner or reader app. The “Quick Response” commonly known as QR Code has become an essential part of our digital life. ![]()
