GlobalTimerExample_Serial.m

% Example state matrix: A global timer ends an infinite loop. It is
% triggered in the first state, but begins measuring its 3-second Duration 
% after a 1.5s onset delay. When the timer begins measuring, it sends byte 2
% to EchoModule1. When the timer's 3 second duration elapses, 
% byte 5 is sent to EchoModule1, and a GlobalTimer1_End event occurs 
% (handled in both cases by exiting the state machine).
% Requires: behavior ports or lickometers with visible LEDs connected to Ch1 and Ch2
% Requires: an Arduino connected to the Bpod State Machine via the Bpod
% shield, and programmed with EchoModule example firmware:
