Flexible State Machine Demo

Here's a demo of my state machine design. State machines are useful for craft with multiple movement modes, or controlling a complex sequence of events, eg. return-to-home autopilot and landing, mech walk cycle, etc.

• Building the machine
  Add as many or as few states as desired. Simply copy/paste additional modules in a row, and connect the 3 places shown by the arrows, with a single memory 'header' connected on the left.
  
  
• Switching states
  Each state is automatically sequentially numbered from left to right, starting from 1. The currently selected state will output an ON value from the red threshold block.
  
  To change state, simply feed the index of the desired state into white arrow input, but this will only trigger for the currently active state. To force a state change regardless of current state, simply feed the target state number into the end of the bus.

This demo file demonstrates a 4-state system, each with a different example of control flow.
