How to create TM1637 Digital Clock with setup Time and setup Alarm functionality

This is a prototype of the time and alarm setup mechanism which I am planning to use in my next digital clock projects.
I hope you find it useful.
If you think of any improvements please let me know. I would be more then glad to look into them and potentially incorporate in my code.

Here is the link to the project details including the code:

List of components:
- Arduino Nano
- TM1637 Display
- DS1302 RTC module
- Buzzer
- Lilypad LED
- 220OHM resistors
- 3 pushbuttons

Nicely done, good explanation. Great, you show how to set time and alarm with buttons.

From India thanks for your inspiration I am 45 not an engineer or computer expect, I am an ordinary technical person doing microwave and television repair. But i love arduino projects by you 👍👍

Thanks Mate
Very helpful
I am going to use this in my upcoming project tutorial
Thanks for sharing.

I made some apps where I set the RTC with GPS. You still have UTC time or the time in China to deal with, so have 2 buttons for such on top (which you could use otherwise, but the date is also something.) The RTC modules can move, so you have many options.

Hi, thanks for sharing. My son and I will build it as his next Arduino project and we will try to add automatic brightness adjust, so the display is bright when there is light, and dim when it's dark.

your code explanations are magnificent

From the UK, thank you for your clock, it looks very nice. I would like to make one using your clock code. But I think I need to dim the display for nighttime.
Thanks again for sharing your hard work, I have been to your link for the project, but it is not available. Bob

Can u program tm1637 without library in arduino

[kentruperthambil]

Hi great project sir! if may I ask sir do you have additional code for also setting automatic time off in this project? thanks in advance

[janecheckk]

hello i just wanted to display real time on this 4 digit display with DS1302 RTC module so i copied your code from 2:44, set the time and brightness but it is not working :/ any ideas what is the problem?

[ABID]

Thank you for the effort.
I wonder if it is possible to make it 12hour format. Can you help?

[Dancopymus]

Cool but, it is much better to use the Buttons without resistors, that is, use with PULLUP in the code; it gets cleaner and less work!

am doing this as my project where can i get the pdf of the codes

Hi again,
how to activate colon blinking every second?

[miguelangelpereyrabogarin]

Hi... could you check what happened to the page where the Arduino code for your alarm clock is, because I can't access it? Or could you send me the project by email, I'd like to be able to make the alarm clock. Thanks.

I watched the related video with interest, I appreciate your effort and wish for the continuation of such educational videos. I uploaded the relevant code to Arduino and ran it, I did not encounter any problems. In this context, I have a question. What kind of code should I write to skech with the screen brightness setting of TM16237?, I'm waiting for your help

[pablonaranjo]

hello, great project, how to make the two points blink, greetings and thanks

[ndolomusau]

hello sir, can i use an LCD 16 by 2 module for this project, am doing it as part of my project.

[fahmipras]

can I use ds1307 instead ?. If I can, what should I change in the code ?
