Hi Robert,
Another great DIY project from you. Many thanks for your amazing work.
I designed my own pcb, based on your design, for the fun and to have it adapted to my needs. (see attachement)
Everything seems working fine except pin 9 and 10 are always up (5v) so the Mosfet for dew channel 1 and 2 are always open and voltage is always 12v.
Do you have any idea of what can go wrong here ?
Also I would like to know if it is possible not to have any display since I'm going to drive the Dewcontroller from my computer.
Best regards
Franck
My mistake, the arduino pin 9 and 10 are not always on, but I have 12v on all the dew channels. I guess my design is wrong in some way. I'm not sure about the orientation of the shottky diode.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Oooooups, I think I found my mistake. I connected the Mosfet drain to the ground :-( because of the net naming in Eagle.
make sure the lcddisplay etc is commented out if you wish to use it without a display
// uncomment the next line if you want an LCDDISPLAY
//#define LCDDISPLAY 1
// uncomment the next line if you want an OLED Display - but you cannot have both display types!!!!!!
//#define OLEDDISPLAY 1
