Is there a new guide on the Adafruit Learning System? Glance over at this attention-grabbing Matrix Portal New Guide scroller. Every hour, this project fetches the latest guides from the Adafruit Learning System and displays them on the Matrix Portal.

You'll use CircuitPython and the Adafruit Matrix Portal to fetch JSON data from the Adafruit Learning System's public API, parse the data, and display it scrolling across a RGB Matrix. 

This internet-connected project can easily be adapted to a REST API of your choice to scroll data of your choice: negative COVID-19 tests, sports scores, positive news headlines, or stock prices. 

Parts

You can use a USB C power supply or a USB micro B with a micro B to C adapter

If you'd like your LEDs diffused (and if your LED matrix is 4mm pitch or smaller), some acrylic may help:

Adafruit carries a number of 64x32 RGB LED Matrices, varying between the space between LEDs (pitch) and whether rigid or flexible. Choose your favorite - larger pitch means the display is larger, width and height-wise but with the same number of pixels, and larger may be easier to read further away. Smaller for near your desk, for example.
