hi
I am looking for a cheap way to controll flow of whater.
the aplication goes like this:
An strong servo(do not woury aboute power consamption) will be conected to a valve. The valve will be conected to a flow meter whit an analog output voltag 0-5v. 0v representes 0l/min and 5v represents 50l/min
whit an other analog voltage signal I will set the flow of wather.
so I need two analog voltage inputs, one digital input(to start control of flow or shut the valve comletly) and an servo output
My question is: Would it bee possible to control this system whit an Micro Maestro 6-Channel USB Servo Controller
ore is it bether to use an mini maestro??
and how complicated is the code for a PID conttrol algorithem??( I am not exactly an programer)
thank you very much for help
