Tides are a fun thing to track if you live near the ocean. The information is even useful for any activity that is tide dependent, like surfing, boating, or just plain swimming. This guide will show you how to use an Adafruit MagTag to fetch and display daily tide information. It will show the times for the high and low events for the day as well as a neat little plot.
After updating, the MagTag goes into a deep sleep until 3 am the next morning, so it can stay on your fridge for a few weeks between recharges.
