#### Requirements - [ ] listens to serial hub for interrupt message (see #37) - [ ] when an event is received send it to the JavaScript using a TCP hub - [ ] send the event `[ "killSwitch", "1" /* state */ ]` - [ ] has a property to check state of kill switch `bool enabled()` #### Other thoughts ``` auto subsystem = new KillSwitch(serialHub, tcpHub); if(subsytem.enabled()){ // kill switch is enabled } ```
