How little did I learn in engineering college.... Not a clue what was done here or how any electronics work. Kudos to you for knowing and making this video.

A suggestion would be a switch between the setting buttons and ground so that it cannot be reset accidentally. A slide switch would be ideal.

Really cool. Thanks for sharing

Creative idea, thanks for sharing :)

Nice, although what happened to the displays colon? kind of looks like it was attacked with sandpaper etc, and didn't light up in the end.

Amazing 👍👍

amazing idea

ATmega pins aren't particularly good at sourcing current. You'd better use 595 as a 7SD driver, or I2C driver IC.

Amazing

Please share the libraries used, I've already installed several and I can't compile them. Thanks

Cool. Btw you could get an ESP32 for half the cost of the Atmega328 plus DS3231 combined, and have internet time sync ability. The circuit would be simpler too.

The ESP32 has a bad RTC and needs many mili amps for WIFI. The ESP8266 is even worse. This requires an IP address to constantly adjust the clock via NTP.

@@jensschroder8214 Hmm could you elaborate on the RTC problem? I'd tested it previously on the ESP32-WROOM-D for hours and it's accurate to the dot. And yes it does draw more current when connecting to WIFI, but it only needs to do it once, say, every day to sync the RTC to NTP. Once that is done the WIFI could be turned off and the power consumption would drop to ~15-20mA, which compare favorably to Atmega328's ~10-15mA. The IP address assignment is handled by DHCP by the router and all that' needed is to call the library function with a WFI access point name and password.

Good video 👍

Hello friend! Thank you for sharing your project. How would it be to replace the two buttons with an IR remote control? Could you share some example? Thanks

is it possible to use a 100uf 25v capacitor?

Nice project

Why are you used only 4R, one per digit? It makes not equal light efect. You should use 8, one per segment, plus colon. It's no critical cost. Extra: use SMD. Decrease clock frequency, it does'nt need such fast speed. 1MHz will be enough. Remove quartc resonator, caps, use internal RC clock. Remove big stabilizator. Use li-po 4V2 battery.

Nice 👍

Thank you 🙏

So nice

laibary problem DS3231 i'm added this file. but not work. maximum function not matching show . plz all library file give me.

Top e.m

What programe feed in ic it is. Not clearly in video

Podrías hacer uno con medicion de temperatura

Super

Can u make alarm clock with this?

No code file in the Drive Plz share arduino code

neat. you have built what i have only dreamt to build, but never actually did. :D but, i would have dropped the xtal and used internal clock instead.

perfect.

Merci pour votre partage. Malheureusement moi j'ai l'erreur à ce niveau ( DS3231 rtc(SDA, SCL); ) Pourtant j'ai installé la librairie Ds3231 et RTC ainsi-que RTCTime et Time

Doing on RTC and Arduino Pro Mini

So the atmega328 ic should have arduino bootloader installed ???

With out bootloader will also work

I have this before, but not accurate enough since it uses MCP but not a real RTC chop.

good

Cool

A 9 volt battery to get 5 volts? You heat up 4 volts to get 5 volts? So 45% loss? Away with the 7805 and take 3x AA, 4.5 volts are enough. Or 4x NiMH = 4.8 volts.

Bro coding is not working. Any suggestions?

Add temperature to the clock design

is it common anode or cathode, code not found on link.
