A strip of LED matrices programmed to display stock prices, weather, news headlines, Discord messages, and more.
I built a 5-foot LED display board by daisy-chaining 8 LED matrices together atop a homemade wooden frame. I hooked these up to a Raspberry Pi that runs a series of Python scripts at boot allowing the user to control which feature they would like to see displayed. Input is controlled from a wireless number pad, which can both enter and exit from a given feature.
The primary feature that the LED display was originally based upon is the scrolling stock ticker that shows 50+ live stock prices pulled directly from Yahoo Finance. There is also a "News" section that displays business news headlines from NewsAPI and a "Weather" section with the current time, weather, and future forecast pulled from OpenWeatherMap's API. The last feature is Discord notifications, which works by setting a Discord bot as online within the few servers it is in and flashing received messages across the screen.
