Relay is not activated reliably

Need Help With My Project
1

Unfortunately my english is not very good.
I have a problem. I have set 4 timers. Everyone should turn on a relay at a certain time and then switch it off again.
That works well. But what I noticed is: If the switching process is a timeout (ESP8266), then the relay does not switch. Only when I reset the Arduino and the “SyncAll” is carried out, the relay also.
How can I ensure that the relays are switched safely? Is it possible to set the pin to HIGH after a timeout?

best regards

Please Write 3 backticks instead of BBCode [c] and [/c].
This is 3 backticks
[c]This is BBCode[/c]

No one can help :frowning:

I’m unsure that the code is wrong.

Declare your pins and initialize your pin either inputs or outputs.

6

OK! So for example "pinMode (2, OUTPUT) ???

7

Did you intend this to be “minute() < 10) && (minute() < 10…”?

That piece of code is not going to work in any case, imagine this @SleXx:

it’s 16:05:50, and your code is not triggered, but it does exactly what your code is telling the hardware to do because not all requirements for your IF statement are met.

What you do there is: IF the first digit is smaller then 10 AND the second digit is smaller then 10 AND the last digit is smaller than 10, do something.

And it should be:

IF the first digit is smaller than 10, format with leading zero
IF the second digit is smaller than 10, format with leading zero
IF the third digit is smaller than 10, format with leading zero.

See the difference in logic?
