Is a Arduino the future?

Whoa there Bob.. tis a mine field your entering..

you could spend valuable days on that and end up having to spend much more time calibrating the probes b4 each use than u would monitoring that aspect manually by slipping a bit of indicator paper in the flow. if u have ever done it , I havent..

and every delay means i have to wait to rip off your work so we cant have u chasing down blind alleys

come on, chop chop.. focus lad

Hang on Fil . . . I'll shoot him down for you ( . . . and me actually )

pH should be measured at 20C . . .NOT at Mash Temp . . . even if you have an ATC meter.

I used to sample the mash directly but now have a set of heavy glass shot glasses that get put in the freezer, remove sample into shot glass . . . take reading . . . generally the temp is pretty close to 20C.

A hot mash is a pretty destructive environment for pH probes

Suitably shot. :argh: :lol: I also don't measure the ph coming out of the mash tun.

Just me googling too much instead of getting on with the job in hand. That's the problem with ordering stuff from China. You have to wait too bl**dy long to get the stuff. Anyway the motor driver has arrived today so I can at least get on with figuring out how to make it open and close the valves. Still waiting on the pump driver and LCD screen, and I am still working on the pressure sensor, although I got it working yesterday, but need a bubbler and figure out how to write the code. I need to figure out how to write the below into the Analog Example sketch.

sensorValue = analogRead( TANK_SENSOR_PIN ); //
constrainedValue = constrain( sensorValue, TANK_EMPTY_SETTING, TANK_FULL_SETTING );
tankLevel = map( constrainedValue, TANK_EMPTY_SETTING, TANK_FULL_SETTING, 0, 100 ); //change these values to tank lt volume

And before you say anything I know it's going to do a percentage. But that could be changed.

As well as including a calibration routine. :pulls hair out: :lol:

think the map command is what u need to look up n around,.. http://arduino.cc/en/Reference/Map

if you want to convert a value in one range to another corresponding value in a different range.

I'm going to start another thread on this called Volume Pressure Sensor so we can discuss a more specific solution.
