QR Code Learning Tool Offers an Inefficienttake onTimekeeping
In a fascinating showcase of technology, a user has built an unreadable QR code generator clock using an ESP32-C3 breakout board, an OLED screen, and a handful of lines of code. This project, while not the first of its kind to be featured on the site, stands out due to its small size and instructive nature.
Unlike traditional clocks, this clock does not display the time directly. Instead, it generates a QR code that needs to be scanned with a phone. The time is pulled from an NTP server and formatted into a human-readable string, which is then converted into a QR code.
The method used to generate the QR code is different from the common practice of packing bits into a C header array and displaying it. Instead, the bits are pushed out to the screen on the fly, creating a dynamic QR code generator. This approach allows for more versatility in creating unconventional displays.
The Arduino QRCode library, version 0.0.1, is used in the project. This library, although widely used, hasn't been updated in eight years. It is based on the QR-Code-generator library by nayuki, a multi-language QR code generator that should cover any platform and has additional third-party ports for various languages.
However, it's worth noting that the term "WTH" does not clearly refer to a specific library in the given search results. Additional context or clarification would be needed to identify what "WTH" refers to in terms of a library.
The use of QR codes in this project demonstrates their potential in non-traditional applications. It's an example of a dynamic QR code generator being used in an unconventional way, such as in an unreadable clock. This innovative use of QR codes showcases their versatility in creating dynamic and unconventional displays.
For non-Arduino projects, the QR-Code-generator library would be a better choice, as it offers more flexibility and supports various platforms.
The author of the Arduino QRCode library is ricmoo. This project is yet another testament to the creative possibilities that arise when technology meets innovation.
