- Hello everyone,
In this tutorial we gonna use DS1302 Real time clock module with Arduino board and also use LCD i2c screen to show date and time on it so you can easily integrate it in your project.
Hope you like it, and if you have a problem/question/suggestion leave it in a comment or contact me, Thanks.

You saved my project too man! Really needed that resistor and I like your library much better.
Thanks for the video. You simplified the task I was facing 😀
Thank you! You saved my RTC. I almost threw it out of the window when it started to display shit numbers, all I needed was the resistor.
plz tell me where did u put the resistor
lotfi DZ in series with the data pin of the rtc to the digital of the arduino
Same here. Tried multiple code versions and got 2008 for year.

JUST GO AND WATCH IT GUYS
Great video! Quite simple and illustrative. Thank you sir, and thanks for the library link!
Dziękuję, pomogłeś rozwiązać mój problem - sterowanie trackerem w wyznaczonym czasie.
Pozdrowienia z Polski.
Very easy to understand. Thank you
It works ! on a nano.
Thank you
thank you so much youre video saved my project, i like it
if i want to show the lunar calendar, what i have to do sirr, can you teach me???
hello friend could you help me, my RTC DS1302 is not storing time when reboot...
thank you
Can you please make a video the shows a ds1302 alarm clock but NO I2C please
hello please can you make a video in which a lamp on at 5pm and off at 5am with the ds1302
What exactly does the resistor do to fix it?
Thank you, very nice video.
Thanks very much! The circuit and the software worked. I tried to use other libraries but could not get it working. May I ask why the 1K resistor made a difference to the correct timing?
To adjust Output Signal... these cheap modules are not that reliable...
Thanks for the video! One question though: what is the resistance value of the resistor you used? Does it have to be a specific value or could it be any resistor?
I used 1k, I think close values should work too, I tried some.
Thanks for support man!
excuse me, how can down the librery for include virtuabotixRTC.h ..? tks..

How to add the AM or PM so we dont get confuse
i hope u're good first of all ty for that video it really helped me a lot with my project at school but i'm facing some struggels i'd like to have a help from u if that's okay ....i really wonder how we can add the names of days of week to the same program
and ty
Hi, I think you just sent me a message on FB, I responded there, you can add "myRTC.dayofweek" combined with a switch case
@@SurtrTech yeah i'd appreciate it if u gave me more detailes because im not very good in arduino language
@@charaf9099 I'll send you an example
@@SurtrTech Hey! do you think you could post that example here :)
@@BreadIsNow I told him about the day parameter and if you want to add it there it will be :
"myRTC.dayofweek" and it goes from 1 to 7
so you can add a "switch, case" structure to associate every value with a day and for example:
switch(myRTC.dayofweek)
case 1:
Serial.print("Monday");
break;
case 2:
Serial.print("Tuesday");
break;
...That's it you can check the switch case structure on Arduino playground for more details
To all the people who say that it is shows the same time continuously, for some reason i made the crystal vertical and i hit it a little and it works now, maybe it can help
Greetings! Working great for me, however I did have to check the address of my display, it came back 0x3F once I changed that address in the code, I have a fine working clock. The only thing missing is an alarm function, it would be great to add that to the mix, since my old night clock was transplanted to our motor home, and I no longer have an alarm clock for those rare days when I need to rise before the damn cat wakes me up at 7:00 AM wanting the damn window open. Oh the joy of old age!
Hello, I already have the code and the wiring for an alarm clock function, the problem is I'm a bit busy these days, I will upload it as soon as possible.
Did it finally, I apologize for the long wait th-cam.com/video/62tHrqMM55w/w-d-xo.html
muchas gracias
Hi, I just did the connections, downloaded the code ant id doesn't work, my ds1302 just heats and shows I'm in the 2000!
Also why do we need 5v when the battery itself is in the module?
Re check your wiring and watch out the pins used, and download the first code which sets up the module, and use the resistor as recommended.
The battery cell is just for when you turn off the Arduino it keeps up the time counter
Oh well I just bought ds3231 that works on I2C, I read it's more reliable than ds1302
Yes it's better, the 1302 has a lot of problems
@@SurtrTech Have the same problem. It just write repeatedly: Current Date / Time: 0/0/2000 0:0:0
@@pablosckX Did you try to add the resistor? Or it may be a grounding problem
Hi there, im quite having a problem with the program because of some errors in the code including the file extension of .h
Im quite new with programming
@@karlmiguelparado3280 That's a library problem, check if you installed the libraries correctly, and then check if you don't have two libraries or more of the same name
Hy i have some problem here, my rtc was working correctly just when showing the time, but when i unplugged the vcc or gnd of the module, the time was repeated to setting time.
Hello, upload the code, let the module count for few seconds, then reset the Arduino,
if you get repeated time, you should first upload the setting time code and then reupload the code without setting
otherwise it will repeat time everytime you reset the Arduino
Hey man, i´m new on arduino, i set the time and date on the rtc with no problem, but in the second code i got this problem:
" no matching function for call to 'LiquidCrystal_I2C::LiquidCrystal_I2C(int, int, int, int, int, int, int, int)' " . in the line after pin´s are defined
it´s the same code from your page, can you help me out?
(also i´m from mexico, so i don't have the greatest english XD )
Did you install the library correctly? Or you're using a different one?
It's a library issue, you can remove your other library and replace it with the one I used, or try to replace that function with the matching function from the library you're using.
oh, i see the problem, thanks a lot, i solved. You're a hero @@SurtrTech
muy bueno
merci mate =)
it set current time automaticly but from where it get the current time ? from the desktop computer ?
You may find some libraries that detect time automatically, by detecting the sketch compilation date and time.
But this library you need to set it first using the function "setDS1302Time" in "setup" then reupload the code without it
ok thanks@@SurtrTech, but this project is useless if you cannot initiat with the real current time, no need library just write a win32 program windows side take the time from internet using sockets or simply windows date api, then send that data true the serial com wich your arduino is connected ans read it with serial.read() and ... voila !
Please make a video on Automatic Vacuum Cleaner such as Xiaomi does.
Will try may be lol
I love it! Works perfectly!
excuse me, how can down the librery for include virtuabotixRTC.h ..? tks..
i didnt add 1k resistor but it works! but there is one problem if you reset your arduino the time resets also, can you fix this please?
Hello, yes the resistor is optional, when you reset the Arduino, does the time resets to what you set it before you upload the code or it gives you some default date/time like 1/1/2000 00:00:00 ?
If it gives you the time you set, you need first to set the correct date and time upload the code... Then comment (put "//" before) the line that contains the function of "myRTC.setDS1302Time" and reupload the code again.
@@SurtrTech thanks, it now works!
Maybe a tip to fix this?
Same time is displaying repeatedly which i have set on the code even after commenting out the lines and using 1k resistor. What can be the problem???
Hello, did you first upload the code with the line "myRTC.setDS1302Time..." then you should put a comment on that line and reupload the code.
If it still doesn't work you could have a problem in the module either the battery is dead or the crystal has a problem
Contact me on facebook if you want.
SurtrTech yes i have done the above steps but still getting prblm
Perhaps if you upload the second code that is meant to run the clock and not just sit the device you may have better luck. Of course I am just trying to read your mind over the thousands of miles that separate us from each other, or rather I am just guessing that may be the problem. There are two codes in the pack, if your download came properly.
Can I set an alarm?
Yes I have an old project for that th-cam.com/video/62tHrqMM55w/w-d-xo.html
Can we get millisecond here ?
milliseconds can be measured using millis() function it's within Arduino library
Works damn well!!
Thank you very much !!
excuse me, how can down the librery for include virtuabotixRTC.h ..? tks..
I get a error when i remove the myRTC.set time line??
Hi, can you please tell me the whole Error?
I think you probably, deleted the whole line which left some "comments" without their "//".
You can just add "//" before the "myRTC.setTime" line.
@@SurtrTech Hi thx for fast response :-) i am just adding // to the set line but im getting error

How to setup DS1302 RTC module with Keypad?
Check the channel.
hello, can you please make a video on how to use the DS1302 Real time clock module with OLED instead of LCD,
thanks. :-)
Okay will do probably soon,
If you can't wait you can check my tutorial where I did OLED + DS3231, and replace the functions
your code doesnt work by me what i need to do
Did you install the libraries, or for the LCD do you use another library? You can change it or adapt it if you want.
