hi,
since month that i wondering if could built a controller for the water floor heater system,
i have solar panel with a pump that bring warm water to circulate on floor pipes.so my goal was built the controller for this, I started with small code after I added more features and ended up creating a board with components.
very soon , it is a temperature comparator with LCD , a button to temporarily turn on the LCD and the other to change the summer / winter cycle.
But when i arrived at finish part i discover a bug, that is when there is a rapid power failure the system does not restart , it is with the LCD turned on but not the system works.
just as I am a curious coder , having not been able to solve the problem, i am asking for your help in such problem.
Thanks

I've seen this when I set the radio power to max and power the LCD via the nano at the same time. The LCD takes to much so the rest doesn't work....
