How to set two states active at the same time?

Wenxin

I want to turn on the LED and deliver water simultaneously after the ITI period, but the two states last for different durations. How can I achieve this?
sma = NewStateMachine(); sma = AddState(sma, 'Name', 'ITI', ... 'Timer', 3, ... 'StateChangeConditions', {'Tup', 'LEDCue'}, ... 'OutputActions', {}); sma = AddState(sma, 'Name', 'LEDCue', ... 'Timer', 0.2, ... 'StateChangeConditions', {'Tup', 'DeliverWater'}, ... 'OutputActions', {'LED', 4}); sma = AddState(sma, 'Name', 'DeliverWater', ... 'Timer', 0.1, ... 'StateChangeConditions', {'Tup', 'Reward'}, ... 'OutputActions', portOutput); sma = AddState(sma, 'Name', 'Reward', ... 'Timer', 3, ... 'StateChangeConditions', {'Tup', 'exit'}, ... % Tup {'Port1Out', 'ITI'} 'OutputActions', {});

Hello Wenxin,

You can add multiple output actions to a single state.
For your application, I'd add both output actions to 'LEDCue':
{'LED', 4, 'Valve1', 1}
and set the state timer of LEDCue to the valve time.
In the next state, keep the LED on without opening the valve:
{'LED', 4}
In the LED-only state, you'd set the state timer to the total LED time minus the duration of LEDCue.

Another way you could do this (albeit more complicated) is to use a global timer linked to a valve as in this example.

Please let me know if this works for you.

Thanks,
Josh
