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

3 роки тому

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:
create.arduino.cc/projecthub/...
List of components:
- Arduino Nano
pl.aliexpress.com/item/328440...
- TM1637 Display
pl.aliexpress.com/item/328678...
- DS1302 RTC module
pl.aliexpress.com/item/149823...
- Buzzer
- Lilypad LED
- 220OHM resistors
- 3 pushbuttons

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

@Witsenburg 2 місяці тому

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.

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

Can u program tm1637 without library in arduino

@ABID5 2 роки тому

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

@marios_ideas 2 роки тому

Few people asked about this. I might do a short video on this. Give video thumb up if you liked it

@erment55 2 роки тому

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

@marios_ideas 2 роки тому

You aztually see that in the code for that video. In the setup function you see command clock.setBrightness(0x0f); You have to play with the hex value passed to that function. I prsume the lower the value the lower is the brightness

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

@marios_ideas 3 роки тому

You need to change this loop. Output time when seconds change and not minutes. if (myRTC.minutes!=minutes){ clock.showNumberDecEx((int)myRTC.hours/10*1000+(myRTC.hours-((int)myRTC.hours/10)*10)*100+ (int)myRTC.minutes/10*10+myRTC.minutes-((int)myRTC.minutes/10)*10, (0x80 >> 1), true); minutes=myRTC.minutes; hours=myRTC.hours; } And then check if the number of seconds is even. So bild an if statement When it is use different command to display time clock.showNumberDec((int)myRTC.hours/10*1000+(myRTC.hours-((int)myRTC.hours/10)*10)*100+ (int)myRTC.minutes/10*10+myRTC.minutes-((int)myRTC.minutes/10)*10, true,4,0); Dont have this connected but you will have look at my tutorial ukposts.info/have/v-deo/f3iHgZicna6L1Ww.html basically shownumnerdec dows not display the colon and it displays 4 digit number which is what you want. So we want to do it every other second

@fahmipras5846 3 роки тому

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

@marios_ideas 3 роки тому

I can see that there is dedicated library for ds1307 github.com/PaulStoffregen/DS1307RTC So download it , install it and check examples that come with it to see if there are any differences in declaring the RTC module. Since the author of this library is the same I would imagine that there might only be a difference in declaration and the rest of the code should be ok

Hi again, how to activate colon blinking every second?

@marios_ideas 2 роки тому

So currently you have this piece of code if (myRTC.minutes!=minutes){ clock.showNumberDecEx((int)myRTC.hours/10*1000+(myRTC.hours-((int)myRTC.hours/10)*10)*100+ (int)myRTC.minutes/10*10+myRTC.minutes-((int)myRTC.minutes/10)*10, (0x80 >> 1), true); minutes=myRTC.minutes; hours=myRTC.hours; } } Where whenever minutes change you redisplay the clock. (0x80 >> 1) is responsible for displaying the colon. What you need to do is to redisplay time whenever second change and for even seconds display colon and for odd seconds display clock.showNumberDecEx((int)myRTC.hours/10*1000+(myRTC.hours-((int)myRTC.hours/10)*10)*100+ (int)myRTC.minutes/10*10+myRTC.minutes-((int)myRTC.minutes/10)*10, true); so without the colon

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?

@marios_ideas 2 роки тому

After connecting RTC run I2C scanner code to see if Arduino sees RTC device playground.arduino.cc/Main/I2cScanner/ Also output the Time to serial monitor to see if time is read , if this does that would indicate the problem with 4 digit display

@janradlinski3787 2 роки тому

it works, thanks for the help

@marios_ideas 2 роки тому

Jan Radliński silly me. I did not read your initial question carefully enough. Ds1302 is not I2c device. I assumed you were using ds3231:( so was the problem linked to 4 digit display?

@janradlinski3787 2 роки тому

@@marios_ideas it seems that i had to mess something up with the code because i just simply restarted the arduino and rewrite the code and it worked. Still great video and good explanation.

Sure you can. It is just a different type of display. Of course you would have to adjust code to exit the RTC read time to a different display
