Sean Hodgins was coming up on 1,000 subscribers to his YouTube channel and wanted to celebrate. As his page is all about his interesting creations, naturally he had to make something for it; in this case, a YouTube Play button.
This “button” takes the form of a rectangle with 104 LEDs on the bottom that display the current number of subscribers to his channel in scrolling text. Control is accomplished by an ATSAMD21G18A chip, an ESP8266 WiFi module, and a Raspberry Pi in order to get around some issues with connecting to the YouTube API.
Hodgins shows off his project in the video below, and has made the code available on GitHub. Though he didn’t get it done by the time he had 1,000 subscribers, the fact that it was nearly 1,300 by the time the clip came out can’t be too bad!
