With a pressure sensor, led and speaker you can turn your Pi into an
invisible dog trainer that trains your dog to get off the couch. When the dog sits on the couch, the led blinks and the dog receives the command “Get off the couch”. When the dog gets off the couch it will hear the command “Good dog”. This application was featured in the Bitreactive blog.
Step 1: Install Reactive Blocks
Install Reactive Blocks form www.bitreactive.com
Step 2: Download the couch monitor from the libraries
In the Eclipse editor on the left side there are two different views: the Blocks view and the Package Explorer view. Make sure you are in the blocks view and select the import button
Select the Couch Monitoring with Raspberry Pi under tutorials.
At this point you will be asked to register. This will give you immediate access to tutorials, modifiable systems and libraries.
Step 3: Understand the system
The system consists of 4 reusable building blocks. The light blue boxes are Java code. If you click on the Java code it will open up in a new window. See if you understand how the system works.
Step 4: Generate executable code
Right click and select build from the context menu. Choose Java SE
Step 5: Export as runnable JAR
After the code generation the package explorer view will open with new new project marked in yellow. It should look something like this (maybe with different project name).
Right click on the exe project / Export and select the CouchMonitor Luanch configuration. Choose a name for the runnable JAR, e.g. CouchMonitor.jar
