I begin my story! Sorry for my English!
I brewed beer like this before:
I wanted to build a compact and user-friendly brewery. Objectives for the project: temperature control, four controlled outputs, program memory, the display voltage and current, emergency shutdown, audible and light indication, temperature, etc. 2 temperature sensor. First for the temperature of the liquid, the second to control the temperature in the overflow into the fermenter. In the future connection of valve control based on temperature. At high temperatures - the valve will close at the set - will be opened. Cooling flow through the chiller.
PID I did not want to use. I decided to do it on Arduino.
My friend wrote a program for the Arduino.
Operating modes: manual mode, auto mode, CIP, settings. The program has five temperature breaks, 8 recipes in memory, check for fluid in the tank, 4 Control output (heating, pump, flow aeration compressor, AUX output).
Program steps can be skipped or paused.
If you connect to a computer via USB, you can control the brewing machine. In the future management of the iPhone and iPad.
The controller now looks like this:
I'll tell you step by step construction.
