I used Presto to create a clock. This clock features a calendar function, slideshow functionality, and the ability to display pre-set messages. Development was highly efficient as I implemented it using MicroPython, allowing me to complete the project in a very short time. Calibrating the clock via WiFi is straightforward, making it easy to maintain accurate time. The RGB565 colour display offers excellent colour reproduction, and the backlight is bright enough to make it well-suited for displaying photos. Additionally, SanDisk microSD cards (I used a 64GB version) work perfectly without any issues. The piezoelectric speaker is ideal for playing the hourly chime, and I have also implemented ambient LED effects on the back to accompany the chime. The aluminium enclosure is solidly built and looks premium, making the finished application feel almost like a production-level product. Furthermore, the touch panel’s sensitivity is excellent, providing a smooth and responsive user experience.
