Materials for a Cat Motion Detoector System
a Cat motion detector system that:
senses when my cat has used the litterbox
wirelessly sends the info to a blinking light on my desk a floor above
has a button on the motion sensor to deactivate itself and the light for a certain amount of time(five minutes) while I clean the box, and then turn itself on after the time has elapsed.
sends a text message to my cellphone(a bit overkill and therefore optional)
