When you complete this project, you’ll have what
we like to call a
Couch
Pet-ato.
This device is a box
rigged with a vibration sensor and recording/
playback setup. You can record your voice, shouting
something like, “Get the &!@!#@ off
the couch!” or a shrill noise of your choosing. When your pet
jumps onto the couch, the vibration sets off the playback.
You can see the finished Couch Pet-ato in Figure
14-1.
So what, exactly, will you be doing in this
chapter? The project involves
1. Putting together the electronic circuit
2. Fitting the circuit into a wooden box
3. Attaching switches, a microphone, and a
speaker
