Cooling and Heating with PELTIER
-
I read a few posts that talk about peltier heating OR cooling and also found one post that talks about both together but I believe it is still incomplete.
i know i need to use a relay to switch on and OFF the peltier and a DPDT/H-bridge to switch polarity on the peltier.
But on the firmware side, i am new with 0% programming knowledge so i need some help there. I read on one post, where David said its not in Heat.cpp but in pid.cpp

But what next.???
