Cloud-connected, programmable devices like Adafruit’s MagTag make it easy to pull live data from internet sources: tides, space launches, transit schedules and more.

Getting your own stuff out there isn’t always so easy though. This often involves server hosting, writing web applications…generally a whole extra layer of knowledge, resources and patience that most of us don’t have.

Why reinvent the wheel? We’ve learned a pretty easy way to do this using Google Sheets — a free, web-based spreadsheet platform. You might already have an account.

One can create and edit lists and reminders easily using a web browser or mobile app…then, combined with some CircuitPython programming, have this information displayed on MagTag. Google Sheets allows multiple people to collaborate on the same document. Or, share just the data feed while the original document is off-limits to others. We’ll demonstrate a couple simple examples in this guide…but if you really get to know your way around Google Sheets, it’s possible to have it (and thus MagTag) showing dynamic data like stock quotes or days-remaining counters. Some potent magic!
