I am working on an article project for IBM Developerworks. We (my son Tristan and I) have decided that we want our (Android oriented) system to monitor:
- presence of water (i.e. for leaks!)
- temperature
- power consumption (Tristan’s idea!).
We will also include a generic analog input value and two ouputs : one digital i/o and an analog value. These could be used for turning on a light, a heater, etc.
Things we would like to add (should we ever build this for real…) include:
- sound monitoring
- video input
- audio out
The architecture will look something like this to begin with:

Phase I - Android to PC to Microcontroller
