NEW GUIDE: Bluetooth Restroom Key Proximity Tracker #AdafruitLearningSystem #Feather #Bluetooth #CircuitPython @Adafruit

A new guide today in the Adafruit Learning System: Bluetooth Restroom Key Proximity Tracker

My office frequently hosts many guests. Restrooms are shared with other businesses on the floor and require a key to access which guests are given and quite often forget to return. We are not allowed to duplicate the keys and the landlord charges a fee when they go missing. Attaching a bigger keychain like a hubcap was frowned upon by management so I came up with a Bluetooth solution using the Adafruit Feather nRF52840 Express board.

This detailed guide provides a complete solution that is much better than a wheel rim, I mean hub cap.
