SO I have the build complete besides uploading the sketch file to my nano. When i try to compile the sketch, I get the error Arduino: 1.8.9 (Windows Store (Windows 10), Board: "Arduino/Genuino Uno"

7_Segment_Clock_v4_SE:6:23: error: DS3232RTC.h: No such file or directory

compilation terminated.

exit status 1
DS3232RTC.h: No such file or directory

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Where do i find those files?

You have to install the required libraries to your Arduino IDE: https://www.arduino.cc/en/Guide/Libraries

Hi, love this clock and am trying to make it. I have been able to print every part besides the diffuser. I am using slic3r and only prints 1.25 mm up and that is it. This only happens to me on the SE version. I tried printing the original diffuser and it works fine. What am I doing wrong?

I never got it to work with Slic3r but I got it to work with Cura.


looks like I messed up the export back then, thanks for pointing out. I've re-uploaded the diffuser - it now slices properly in slic3r. :)

Love the design. Can the 2 segments attach next to each other, instead of on top of each other? Trying to find the smallest 7 segment, but it's for my daughter and I want to keep the numbers next to each other like a normal clock. Maybe just turn it to it's side? But, then the legs won't work, right?

the electronics case won't fit, as the holes used to connect everything won't fit in a horizontal mode. I modified the case somewhat so you could use it for a horizontal setup. I've just cut off a bit of the old parts to hold the feet so the attached ones should work. But please note: I have not tested this by myself, but can't see anything wrong with it right now...

I've never "shrinked" the center part from the original clock so here in horizontal mode you'd end up with 4 digits and nothing in between, I'm not sure how good that'll look in the end. But if you want to try it, here's the parts :)

Two modules end up at 282mm x 118mm x 60mm (incl. feet).

Thanks for taking the time to respond and also edit your files. You're right about not having any colon in between, it may look a little weird. Maybe I can somehow stick 2 regular LEDs in there. I'll take a look at your stl files a little later on. Again, thanks a bunch for what you are doing.

Do you have an Arduino file that does not have any WiFi?

What do you mean? None of my currently published things uses/includes any WiFi functionality...

Hi. What if i dont remove charging circuit on dt3231? I complete the clock. But i have a problem :) Clock doesnt change. It show time when i plug usb but not change. I think it freeze. Is it possible ds3231 or another issue?

Hard to tell from the distance... ^^

Make sure you didn't accidentally swap the connections from SDA/SCL to A4/A5. Does the clock work without the rtc connected? It should work without it (it just starts at 12:00 every time power is disconnected).

I can't tell you what will happen if you don't remove the charging circuit from your module. I don't know which one it is and I don't know what battery it came with. I had some batteries burst within the first few months, so this is one of the things that might happen.

Thanks for your reply. I found the problem. My nano (clone) was broken. Not rtc or code broken. My nano freeze. I replaced nano and problem gone.

What's wrong with the one hundreds of others have downloaded already?

Do as kiwix suggested or simply download all files and take the INOs from the ZIP files...

all found. thanks a lot

What about taking a look at "Thing Files"?
