Total Newbie here so please excuse my mistakes.
After a couple of pointers...
Hacked a fridge and got an Arduino controlling my beer fermentation temperature.
So far so good.
Installed LCD to display temps and heating/cooling on/off
But I want more precise temp control hence PID.
I have a working code for the PID part, which I don't fully understand, but working on that,
My question is.... Do I simply need to work out the PID side and then combine the two sets of code to make this work?
Obviously after I get to grips with PID
Thanks in advance
