A Raspberry PI monitors the tweets to @OurCatDoor.
The PI's GPIO acts as inputs to a PICAXE 18M2 which controls five servos on a robot hand. You can control the "The Hand of PI" by sending a tweet to @OurCatDoor. If your tweet includes any of the text below, the "Hand of PI" obeys your command.Valid commands are (lowercase):
one (holds up one finger)
peace (shows the two finger peace sign)
three (three fingers up)
hookem (if you are a Texas Longhorn fan this one makes sense)
fist (the Hand of PI gets ready to fight)
open (ready for a 'high five')
Go ahead, try it!!! Send a tweet command to @OurCatDoor to let us know you were here.
