Hi!
Are you talking that relays are OFF when should be ON and vice versa?

But now, the clock does not mark well it is as if voltage is missing, i come out as you can see in the photo. I connected and mark well the hour but after half a minute is as well. I have a doubt, have if you are going to be why do in the ULN2803 that I put it in the post connects the gnd capita there not to put the 5v to pin 10 of the ULN2803 is free?

Hi!
Yes, the pin 10 isn't connected as you can see on schematic.
You have other topic to talk about power supply.
viewtopic.php?f=24&t=297
For now the initial question is solved.
Best regards.
