I want to be able to set the time using the serial monitor, but I can't seem to get it working with my code.
The code im using is "Setserial" by "JChristensen"
This is my current code

I can not confirm you issue. When I run your program and enter the year,month,day,hour,minute,second from the serial monitor I see your RTC set to: message and the time is updated correctly in the rtc.

Hi,
I can say it does work (sort of), but after 1 read it resets the time to 31 DECEMBER1999
I don't know why? How do I fix this?
Many thanks for all the replies I got so far I really appreciate it!
I set the time to 22 OCT 2022 but after 1 time the program has looped it sets the time to 31 DECEMBER 1999
You shouldn't use external links like that. There is a possability that these links are malware-infected.
You can attach code that exceeds 9000 byte as an *.ino or a zip-file you can attach pictures to the postings if you click on preview you get an addtional option to manage attachment.
As long as you just write such short messages the forum will be unable to help you because the non-existant glas-pheres of the users (including th evirtual ones on the screen) do not show were your error is.
You still have to still have to provide all the details what you did do
And this is only the code for the RTC (by JChristensen). Im trying to just set the RTC using the serial monitor, but this code resets the input after 1 loop and I don't know why. I don't fully understand his code but I haven't found a code thath has (kinda) worked so far yet.
but this code resets the input after 1 loop and I don't know why.
Neither do I. When I run the code you posted, it does not reset.
I do not see how the code can reset if there is no serial input.
Indeed, the last line of tijd_instellen() throws away any additional characters in the serial buffer and clears it with
while (Serial.available() > 0) Serial.read();
Are you using the serial monitor of the ide?
You previously said that when you run the library example to set the time from serial without any additional code, it works correctly. Indeed, I have worked with Jack Christensen's code extensively, and it is rock solid.
When I test your code, I am not physically connected to a temperature sensor or stepper, so you might try to remove those pieces of code or disconnect the outputs to see if you can avoid the reset.

I found what was wrong, I tried the standalone code. And it works fine now (It didn't previously idk why).
Im finding out what went wrong putting JChristensen's code into mine.
Thanks for the replies
