- This video is uploaded as most of fans wanted a detail video about the project. You can watch complete tutorial by this video.
This project is based on arduino RTC module. It can be stored memory the real time. You can use normal LEDs but need to use same color and same brand of LEDs, If you have selected different kind of LEDs, some LEDs may be glowed than others.
Most of arduino beginners had prepared this project and also successfully completed.
I hope you can make this project and enjoy the leisure.

Thank you very much for share you project! Its very nice and useful!
you are welcome
Hello, to connect the segments a-b-c etc, that you use as a common anode driver a 1k resistor and a bc547 or double transistor bc547 with bc557
You can see the diagram in details by visiting the web like given in the description.
Nice project. I shall assemble the clock.
yes , try it
nice project and thank you for your coder
Thank you
Awesome which seven segment display you used in this anoad or cathod
This is an old project. I think I have used common anode. But you can use either ways .Read my web tutorial. Now I am working on a big LED clock with new upgrades. I will upload the details once it is completed. 😀
@@SetNFix great sir then I try to make new one sir pl add temperature also ..when this video coming sir
nice work manh
Thank you
Thank you....very nice....🙏🙏🎉🎉🎉

Thanks to you sir, I have successfully completed the building of the clock,it works fine but where did u connect that red led for 24hrs to? Which pin did you connect it to?

Great job
@@SetNFix but, after load sheeding the memory was lost. What can i do now? I have installed 3v battery for rtc module also.
@@ibrahimhossainet There is an LED in the module. is it blinking?
Really great 👍
Thank you
sir i mead this clock the only one problem when i change the 12 to 24 hour 1 to 12 am timer is display but the 1pm to 12pm not display but the serial display right value but display is not what is problem but the 24 hour time is prefect display
What is showing?
Thanks for sharing this fantastic project.i completed the project.every segment with 5 LEDs,6 digits,Arduino Nano,power 5V and 2.5 Amps. i have issue with the 1 and 2 digits of hours.all 7 segments are on and flicker in unison with the last digit of second , with different brightness.the other four digits are running like a charm .what could be the issue.Thanks a lot.
deactivate the code Serial.begin
@@SetNFix I appreciate it.i commented the Serial.begin() in void setup.the problem i am dealing with has to do with the hardware b/c the code works like a charm on the same clock i built before with red leds this one with blue leds.Thanks a lot for your time.
What is the principle of using double transistor, in Anode pin or Cathode pin of LED of SSD. Please inform me.
Arduino pin gives you +5v signal. you can use only one transistor to give negative voltage to an LED. But if you want to give +5v using a transistor, you have to use two transistors.
good project👍
thank you
To this program ds3231 rtc Are you playing modular, sir?
This is Ds 1307 module

Can i use 2n2222 or bc547 instead of D400 npn transistor?
Yes. you can use the both. better 2N2222

Thank you sir , i completed the project working fine, but a small problem when clock is running in 24 hours mode, when i switch off supply , the clock is switching over to 12 hour mode, please help
yes. it is because your data not keep in the memory. But you can do it using EEPROM codes or simply using a push on/off button switch.
my project dont run why
Thx for ur support I have made this ...one problem I'm facing sir when clock is 24hrs then second led is not blinking is still and when 12hrs mode then its not working pl help in this is any change in code pllll then my clock work well

HELLO BROTHER, THANKS FOR UPLOADING VIDEO. AFTER WATCHING YOUR VIDEO I DESIGNED A CLOCK FOLLOW YOUR CIRCUIT AND SUCCESSFULLY MAKE A CLOCK. IT WORKS WELL BUT CLOCK HAVE TWO PROBLEM FIRST IS AFTER ONE DAY TIME BECOME INCORRECT AND SECOND IS CLOCK STOP WORKING AND SECOND LEDS ARE BLINKING AFTER RECONNECT POWER IT START WORKING, PLEASE HELP ME TO SOLVE PROBLEM. IAM USING TINY RTC I2C AT24C32 DS1307 REAL TIME CLOCK MODULE.BEFORE YOU HELP ME TOMUCH .THANKS
Time delay can be adjusted changing the value of brightness. But due to the deference of the quality of the components some delays occur.
When arduino is connected to PC, signal transfer between PC and arduino, therefore LED may blink.
Can we make with out transistor ???
yes. you can
Dear sir,I have build the proteus file according to your code using both CC & CA display & load only ssd hex to arduino.But its not working properly.Please sir help me.I will be obliged to you for ever.
Did you use the transistors ? and is it supported the libraries ?
I have no use transistor in proteus file. Line number 33 when RTC_DS1307 RTC; library file showing error. When I erase RTC_ & only DS1307 RTC; having code successfully compiled.Please sir help me.And which type display I should use the given code?

hello sir, I built the clock from your video...it was very helpful project....sir I detect an error while compailing.....if you dont mind plz help me to solve the error..//"lightNumber(toDisplay%10);"//...not declerd in this scope...plz help me sir
Did you add all the libraries ?
How problem code,....( case label '0' not within a switch statement) plz help
Is there an error code?
Nice project sir 😊, but in went to add extra zero in hours segment, for example - clock showing 8:30:00 but I went extra zero before 8 , like- 08:30:00
Any solution sir ?
yes, you have to enable 1st digit. change the code if the timp value is lover than 100000 to add a zero in front of the timp value.
@@SetNFix ok
Sir I had done your project .all function are normal but I'm facing problem in 7 segment display brightness. Pls guide me to increase the brightness in code.
How much current you have used?
Actually i modified a 50 ton weighing machine remote 6 digit 4 inch display for this project . It built with a AVR controller and uln2003 display driver. i removed the 40pin AVR controller and applied signal from arduino nano to corresponding pin for display. when i run the project it work fine but with dim display. when i changed the display brightness in code from 20 to 100 the brightness increased, but it affect the seconds. mean that after 1... display jumped to 3.. and 5... so on...
hope the current and voltage is sufficient, since its already in working condition as a weighing display.
@@pandiarajan464 Yes, you can only fine tune the brightness of the LEDs as it is happened to jump the numbers of seconds due to a changes in brightness.
If you have changed the numbers of LEDs, calculate the current requirement for one SSD and check the maximum capacity of current that the Transistor able to handle. When the LEDs are increased you may have to change the transistors suitable for the Display as the transistors are working as ultra-speed switch to On/Off the displays. And also check the diodes and regulators as they can handle limited current only.
@@SetNFix OK sir thanks for your fast reply. Let me check the components as your info.

Clock working fine,but I have question
1. Clock showing 0:00 instead of 12:00 at midnight?
2. PM LED glowing at 1:00PM instead of 12:00 PM?
In intro video your clock showing 12:10 with PM LED glowing but in my case PM LED not glowing at 12 PM.
Please reply
Any help please?
since it it 24h, it shows 00: instead of 12. you have to change the mode to 12h clock to 24h
Ok thanks for your reply.
But in my clock PM LED is glowing at 1 o’clock in the afternoon, why not at 12 o’clock. In the video PM LED glowing at 12:10.
Please explain.
