please help me wit my electrical engineering homework : temperature control and watering system using labview and arduino

[dfebria46]

spesification : 1. max temp : 28 celcius (when temperature is more than 28 celcius, fan ON) 2. min temp : 20 celcius (when temperature is under 20 celcius, heater ON) 3. watering system : aquaponic (grow plant and fish in separate tank but connect each other). Plant roots help filter water for fish. Fish poop for plants fertilizer. So I need a pump to distribute water Please help me create VI file simulation.. I'm sorry I'm not fluent in English. May God bless you all

That's not how it works.

You post what you've done (the .vi) and ask a specific question and we'll help you over the hurdle.

E.g. you can check the temperature in a loop (with a delay), wire the result to a case structure, and if 28.. activate fan, if ..20 activate heat, if 21..27 turn both off.

Please keep all the discussion in this thread. The duplicate thread in another board is not appropriate to the question.

The VI you posted in the other thread has no independent control for the heater. If the blower is off the heater is on. Do you really want the temperature to continually cycle between the limits?

Consider learning about the state machine architecture. With a suitably designed state machine you would probably only need one loop and the fish would be happier.

As Yameada said, we will not do your homework for you but will help you understand how to use the tools (LV). Please ask specific questions.

Hint: Use booleans for the lower shift regsiters in your loops.  Much simpler code.

LabVIEW is a great choice for simulating this (no Arduino required) but a terrible choice for implementing the system (where an Arduino alone will fit the bill much better- low power, all solid state, no expensive software required and plenty powerful for the task).
