Making a Reddit Upvote Notifier
The Arduino Yún's ability to connect to the Internet introduces many new possibilities to traditional Arduino development, such as capturing data from the web and making use of it inside of a sketch.
This project will demonstrate this ability by monitoring the number of upvotes accrued by a Reddit comment thread and alerting the user when new upvotes are added.
Many companies offer application programming interfaces (APIs, for short) that allow third-party programs to access their data. Reddit, for example, provides an API that gives detailed information and statistics for posts, comment threads, and users.
This project uses a Python script on the Yun's Linux side to read the current upvote count from a comment thread using Reddit's API. A skech running on the Arduino side will track this number and display a notification message on an LED matrix every time a new vote is added.
