It is an example for automatic watering the garden.
It can be easily changed for your own hardware.

Here is the comment from author of this program:
This program I have installed on my home garden. I have 8 watering zones (really only 6) and one motor pump. I can program DOMO to watering at determinate time during a programable time all zones. Also start or stop process from keyboard.

In addition inputs can start manual watering on a zone.

All can be done using only 3 buttons:

LOW BUTTON = Next option, increment variable, ....
MIDDLE BUTTON = OK, Accept, ...
HIGH BUTTON = ESC, Abort, ...

The program is intended for the new DOMO board from IBERCOMP, but the program can be rewritten for your hardware.
