My arrival alerts them, as I approach the door, with a similar method. They greet and seat me, then serve my freshly heated dinner. With another tap, I flirt with the waitress, and auto-tip her for the friendly smile. Her response is another silent stealth signal, sending me her number and facebook links. Final tap, and dinner is paid and valet parking has been alerted to bring me my car, before I have even stood-up from my seat. The final signal vibrates my foot again, letting me know the car is ready, parked and waiting. I head home for the night… (Alarm set by my presence, as I enter the room and remove my shoes.)

All without having said a single word.

Ok, a little “out there”… But, not unrealistic.

BTW ++200 for using Arduino for this. (FYI, the smaller 8-prong chips may be all you need, looking at the wires you have setup. That saves a LOT of room. Look for “minimalist arduino”, or “tiny arduino”.)

P.S. I came here looking for your ajax animator, and you blew my mind with this instead. Dude, you are like mentally 40 years old. You make me seem like I am the one in high-school, reading this stuff. Apply for a job with google. They already know who you are, trust me. They do and fund stuff like this all the time. (But take me with you. I am not as lucky to have your mind for this, but my mind has other uses, related to application.)
