Compact LED display unit that functions as cryptocurrency ticker and doubles as a realtime YouTube subscriber counter.

This project was created for our 100,000 YouTube subscriber milestone. Watch the video below for an overview of the project, demonstration of what it can do, and a Q&A special at the end.

Combine the LED Displays
We’re using two 4-in-1 Max7219 8x8 LED displays for this project. Max7219 modules can be daisy chained together to display long messages. The 4-in-1 modules come pre-soldered together, but we need to combine both displays to make one with 8 elements for space to show our cryptocurrency ticker. We snipped the wire ends off some old resistors to make a couple bridges between the two displays.”
