arduino 7 segment clock with rtc
Please visit my instructable page for the circuit diagram, so let’s get started. You will require these components. We are using an Arduino Uno for controlling the circuit and for 717 display or SSD wit, common anode, pins and three SPD pieces start off by cutting this pair wise. In the length of C Center fill up the coating of the spare wires and cut them in small pieces, bend them to form for small jumper wires, be careful. While doing so, you may get hurt. We will require this to solve the common anode themes of the displacing the plate. After you have finished, making layout lip read, good started turn to medium forward and keep a gap of minimum of five fingers between them. Inserting all the G wise is time to insert year systems inside the SSDs in such a way that the common pins of the displays are in the same book as set of jumper wires and repeat the same with the other. Displays now connect the zero pin of the first display from the left to another roll. You now repeat the same process with the other displays in such a manner that the european of the first display of the left, the right and the fourth display the BAM right. What is number one? The leveling up now, it’s time to copy one. Cue first insert the resistance, as if your resistance is time to connect the thickness of started by connecting the note pinch of, is this repeat the same process with the bottom and the top pins of the displays now extend the BFG.
The first display to the other rules now repeat the same process with the EDC. Dot means I have to load extra wires to the legs of the SPD. Switches for good connection now insert a switch to the upper row today. Small jumper wire connecting one of the legs of the ski with a rope you now in 30. Second key connecting one of this leg to the jumper wire, now insert another example where you, through this kanaka troll and to Vienna, No now insert the third key. Such a manner that one on the leg is connected with the second jumper wire now it’s time to connect our prototype to the Arduino start by connecting the jumper row to the ground, pin or password. The left leg of target goes to the k13. The left leg of the second team goes to the pa2 of the other, and the left leg of t1 goes to the Queen in auto fire. Now, it’s time for coming the segment’s to the Arden pin a goes to pin to Padrino in will go to print 3, pin see two three four pindy to pin five Big E 2p6. We have between 7 pin g 2p neg and the dot pin goes to be nice. Now connecting the energies windows go to, pin 13 entry goes to pin 12 into those who’ve been 11 and then one plus 15 and our circuit is complete. Now plug the Arduino to the computer and upload the code, get my project page for the source code and the circuitry is link, is given below and is absolutely free.
After the code is approved, you can see the displays coming to light along with the blinking dots. First key is voyageurs, while holding it praise the our key or the mini to change it. It’S easy to make and fun to play.

‘hour’ was not declared in this scope
kindly guide me need this code now
i add the time file to the library folder on arduino
Sorry Hammad for such an error. actually the Time library i have used was for old version of arduino ide. it was update after arduino ide 1.6.1 version, hence the error.
here is the link to new updated library, but before you use it delete the Earlier Time folder from libraries folder
C:\Users\lenovo\Documents\Arduino\libraries and also from
C:\Program Files (x86)\Arduino\libraries
now dowload the zip file and add it to arduino,
https://github.com/PaulStoffregen/Time.git
To add it go to sketch->Include Library->Add .Zip Library and find the zip file.
after that go to sketch->Include Library->Time
And it will work.
Sir…..how to convert 24 hours to 12 hours format??????
thanks…. can i get your facebook id for rapid conversation??
Tips & Tricks it’s Madhab Sharma madrajib
a sent you A message on facebook from Shariful islam..did you get it ?
Tips & Tricks yes I got the message
i have faced a problem…after 24 hours time is set 00.00….how can i solve it???
Hi, how can I add RTC to the program and 12-hour format?
Thanks
sir code not working, all segment lighted only point dot working. the bytes in upload in ur video is different when i upload ur code download. tnx
sir please send me code to my email rajib.madan.sarkar@gmail.com
Rajib Sarkar
It is right there in the description. Here is the link: https://www.instructables.com/id/How-to-make-a-Arduino-Digital-Clock/
sir the code facing error
please send me code separately
Code is all right Rajib , it’s the Arduino ide that is messing up. Update it to the latest version to make it work.
i need your help for this digital clock
Are you placing the buttons on breadboard ..?
Check the connection may be the button is not connected properly ..
MadRajib Lab I cheked it but i think no probpem in the conection
Okay then did you try holding the set button and then pressing the hour and minute buttons ?
MadRajib Lab i ,ll try
To change the hour and minute you have to hold the set button and then press the other buttons.
Plz mention the changes to be done in code and connection if i use common cathode display
Link for code please???
The link is in the description !
I m trying the code in mobile phone using aurdino droid.. There is an error
Return code is not 0
See this video how to add libraries to the app. It might reslove the issue

Sir push battan is not working , what can I do?
What if I want to put it in my car (12v)…which analog pin should go to the car key switch?
i have made the clock… but the push button is not working… what can i do???
not working code
This is urgent!!! Please help me sir. I am making this clock for a school project that is due in 2 days. The spdt switches are not working. I have clearly followed your instructions. But I still can not set the time. There is no problem with the code. Please help me sir I dont know what to do.
Sourish Pardhan,
1. Have you checked the switches if they are working fine.?
2. The connection of switches to the board are all okay? sometimes due to the loose connection, they might not get connected to the board.
3. Are you using a breadboard? then the pins of SPDT are small and won’t reach the board connecting holes. Add extra thin wire as I have added to the switches.
Dear Sir, I am using a breadboard and spdt switches are properly connected. I actually just realised that spdt switches are working fine. However the displays are not properly showing numbers when I am setting the time. Please help me with displays issue.
Sourish Pradhan, how are they displaying the digits?
Sir, the digits always look like an 8. Sometimes when I am pressing the switches, the digits look like a 3 or 6 only. I cannot see any other numbers on displays.
Could this be due to an issue with the wires or resistors? Do resistors have positive and negative sides?
Or is this an issue with the LED Displays?
Most probably that because of connections issue. Try to remove all the displays and try to connect one and test . And add one by one and test.
Just a little clarification…will this work if I power the Arduino with a power source, and not have it connected to a computer? Also, just give me a few tips on making it standalone, i.e., without the Arduino board. I guess just the Atmega 328P should do the job?
yes, indeed it will work.
You can make it standalone, but you need the 16MHZ crystal, two 22pf capacitors for the clock and Reset register. And a voltage regulator for 5 v for the board.
Here is a link in that context!.

@MadRajib Lab Thanks…ya I know about that. But was a bit unsure because the program has Serial.begin() function. That won’t need a serial monitor.. right?
@Arijit Kumar Haldar don’t wory, there is no issue with that.
bro please solve the coding problem you have :

This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.
———————————————————————————–this is the error please solve it and also if processable use rtc to keep clock running when on power failure

Code not working, compile error
What error is it showing
Good video bro.
But I have a question,
Sir, I am making an arduino digital clock, but I don’t want to keep the USB attached .If I use a 9v battery, where do I attach it?
Or should I just attach the other side to a power bank??
Please reply
