Fans of the Harry Potter movies will remember the Weasley family clock that tells where everyone is. For more about the clock see the Harry Potter Wiki.
Of course something like this makes for a great project. We have rounded up four versions of it below and what they use to make them work.
Each project uses a different microcontroller but the first three also use a service called If This Then Than (IFTTT). This is a service where you create recipes and can make location based ones. For example, If you enter an area, then send a text message to a phone. You then define the area on a map and save the recipe.
The last project used a service called (Message Queuing Telemetry Transport) MQTT instead of IFTTT service.
