Me and some friends are looking in to automating our dosing tank and im wondering if this is even possible to do with arduino?
Is it possible to:
Controll temp by turning a fan on and off? With settpoint
Controll dosing of pump with EC (electric conductivity) value?
Controll on and off a mixing motor. Settpoint is sequential. every hour for example.
Controll PH by turning on and off pump.
And her is the kicker, can this be linked up to some alarm that can be sent to our mobile phone? LL,L,M,H,HH
The hope is to learn enough to have 1 board where we can see and/or controll the system from a phone?
If these things can be done by hand, they can be handled by an Arduino, but the hardware and the programming need to be created by someone who knows what to do. This should not be attempted by a beginner, and, while asking is a very good thing, the fact that you needed to ask suggests that you are a beginner.
Beginners should start with the tutorials and attempt simpler goals.
Yes it is possible and I agree with vaj4088. You can start by working with each part of what you want then when you have each working you can combine them. Maybe start by simply turning the fan on and off. You can use a LED to indicate this, if you drive the fan be sure you know what your doing with the mains power. If it is a low voltage DC motor it is not the safety problem that a mains motor would be. I would put the first line of your code as: // are the Grounds Connected?
If that is true most of your problems will go away. There are a lot of examples etc on this web site including code for you to start with.
Good Luck & Have Fun!
