Button state diagram
With reference to the table above, the button states operate in a fixed state process.
State 0 is the default state where both the green and red led on a button is turned off
and associated outputs are in an off position.
The left branch on the diagram below shows the st ates when the user wants to turn on
a main output, e.g. the main lantern. By pressing the button for less than 5 seconds, the
button changes to state 1. In this state a message is sent to the corresponding output,
and the led flashes rapidly awaiting a con firmation from the output module. Another
press on the key at this state will return to state 0 and a message to turn the output off.
