The Covid Tracking Project (https://covidtracking.com) tracks all US state data and collates it into one report. This project for MagTag wakes up once a day at 8pm, about a half hour after the data is posted daily, and displays the latest data report.
In between check-ins the MagTag goes into a deep sleep mode so it will run for many weeks on a charge
You'll want a MagTag + battery, and magnetic feet to attach it to your fridge or other metallic surface
You can also get the parts separately
- WiFi network (802.11 b/g/n)
- A desktop or laptop computer is required for initial setup: any text editor will suffice
- An Adafruit IO account. If you’ve previously purchased from Adafruit and created an account, this is automagic (and free)!
