LEDマトリックスで光るわぷー(WordPressで指定編その1)
The document describes how to create a LED rollsign display using a Raspberry Pi and RGB LED matrix panel to scroll through images of Wapuu characters. Key steps include collecting Wapuu images, arranging them horizontally, connecting the LED panel to a Raspberry Pi with an RGB Matrix HAT, and writing a Python script to retrieve the image number from a WordPress page and display the corresponding image on the panel. The display can then be run automatically on startup by adding the script to the Raspberry Pi's crontab.
