Hello Sterretje
I've got a LCD like this :

(but before having it, I had freeze also)
a RTC1307 like this :

(but before having it, I had freeze also)
a relay with optocoupler like this :

Have a led to send a signal that tell some loop is still running (although the LCD send the seconds too)
the power supply 9v like the one I posted on my former post.
with decoupler devices.
I'll make the drawing schematic tomorrow.
This is a device to power a bell, a kind of chime, 4 times a day. 2 calls "make food" and 2 calls "come to have lunch/dinner"
Code is still a little dirty...
This code is currently running on 2 Unos. One on a Chinese Uno is working perfectly for ... 1 day and a half on the real bell, and another is genuine Uno working on a buzzer at the output (no relay).
This second one had a bug today, it starts ringing almost continuously, it was because the "test" pin8 was configured input but was not connected to anything, even without a wire plugged into the arduino connector, but it was sensing some electricity from the air and detecting. Now directly plugged into grnd, no problem anymore.
but as you can notice, I try everything, including the watchdog (not in use now ) but the watchdog did not stop the uno from freezing.
I also made a code for making my gate automatic (not descripted here) same problem. Was working properly, but after a certain time, will freeze.
Comments are in French, I hope it's not a problem ?
Now I send the code :
