Ping phones and tablets of friends in your network with an arduino with ethernet shield, when a phone or tablet is detected send a pushover message to your own android or iOS phone or tablet.
This way when friends visit you, you know who is visiting you or who visited you when you where not at home.
The idea is to receive a message before they even ring the doorbell because they are detected on your wifi network.
All you need to do is give these friends a static ip address in your router from their phones/tablets mac address.
If your friends get new phones, you never have to change the code, just assign the new mac address of their new phone in your router.

PingMaster project by M.J. Meijer 2014
Ping phones/tablets of friends in your network, when a phone/tablet is found => send a pushovermessage to your own phone/tablet
This way you know who is visiting you when they make contact to you wifi network
Also usefull to see if friends visited you while you where not at home
You need to give friends a static ip address on your router from the mac address of their phones/tablets
