Arduino LED Matrix Clock 

Thanks Davy, I'm Paul. Glad to have you here.

I am an electronics software engineer and I find coding daunting at times.

Glad I'm not alone!

@@gartmorn Hello mate ... Definitely You are not ... I am just a humble 60 Years old Electrician with a passion for Microcontrollers too , but NO way to Understand what's going on on those "mambo jambo" - "Alien" Lines off cod ...🤣😂... I have NO time or Knowledge to Start from the "Beginning" with such a Huge World of Coding ... maybe in the next 3 Life's from now on ... I Hope 🤣🤣🤣 ... Nevertheless I still like to "play" with electronics components and Arduino boards ...

Thanks Javier!

Thanks

same problem... I cannot find a clock code to work with 2020 lib and FC16.... I think it´s on propous... to panish who buy chinese models ;) 3 days looking and trying everything and cannot have a clock going...

Dan do you have a solution already?

@@jpcme2002 No. I think youtube stripped my link to the solution

Another Maker can you send to jp200tdi@gmail.com please

not to be mean but your pfp looks like a mugshot 😳😳😳

It's just the camera, looks fine IRL

The DS3231 real time clock module has an internal temperature sensor

+Bob Wareham It is possible. I didn't get into it. But that scrolling function is available in the library.

bool h12, PM, Century=false; // increase this byte year, month, date, DoW, hour, minute, second; //Clock.getTime(year, month, date, DoW, hour, minute, second); //replace this int second,minute,hour,date,month,year; second=Clock.getSecond(); minute=Clock.getMinute(); hour=Clock.getHour(h12, PM); date=Clock.getDate(); month=Clock.getMonth(Century); year=Clock.getYear(); DoW=Clock.getDoW();

hi Fercho, DS3231 has internal temperature sensor.

+Palash Karmakar you don't have the ds3231 library installed.

yeah same here

I can't help you there.

learnelectronics ok no problem you have already solved many problems by uploading your great videos.

Probably that the SPI MOSI pin should be pulled down to ground, though I can't recall what part of the video that it, so he might've misspoke, as I'd expect MOSI to be connected to the peripherals so the master make requests to them.

Mohammed Zaman of the ide? 1.8.1

not very difficult, print ":" and then print " " (space) in the same space with a 1 sec delay, there you go. of course there are other ways

Bharat i will try. thanks

+Frode Molland sounds like you are missing a ;

It stops with this now byte year, month, date, DoW, hour, minute, second; this is direct copy from the code

chang the code .. Clock.getTime(year, month, date, DoW, hour, minute, second); to: int DateTime=(year, month, date, DoW, hour, minute, second); I just cannot test it as i am not at home for next 2 weeks, lemme know if it works :)Like Adam bluebottleyellowboxyellyfish sad and use this Libary github.com/jarzebski/Arduino-DS3231

Hi! I'm getting the same error at int temperature=(Clock.getTemperature()*1.8+32); after changing the code from Clock.getTime to int DateTime. Can you please help me? i'm using the Library that you linked. Thank you

make sure you dont have another version of the DS3231 libary installed.

William Gibson Still doesn't work. Thanks anyway

Use the library DS3231 by Eric Ayers

bool h12, PM, Century=false; // increase this byte year, month, date, DoW, hour, minute, second; //Clock.getTime(year, month, date, DoW, hour, minute, second); //replace this int second,minute,hour,date,month,year; second=Clock.getSecond(); minute=Clock.getMinute(); hour=Clock.getHour(h12, PM); date=Clock.getDate(); month=Clock.getMonth(Century); year=Clock.getYear(); DoW=Clock.getDoW();

what do you want the IR Remote to control? Setting the clock, date, year?

​Hi Donnie, first, thanks for the reply. Yes, set the clock, date, year. And if possible, make the colon flash. I would be very grateful to you because I have been looking for such a project but never found it! Thanks again

THank you. Sometimes I forget to upload sketches...as is the case this time. Here you go: www.dropbox.com/sh/29i8797cpc68t9f/AABGn1UiflF7d4zqU6DGjLoea?dl=0

Thank you!

Mohammed Zaman I can't help you with PC configuration issues. but I believe the sketch is in the wrong folder

DS3231 library is missing or not in proper place

DS3231 by Eric Ayers

Thanks! that worked! Had to replace all wire.send with wire.write and rec with read but it compiled in 1.6!

jacekf ahhh, ok. I'm using 1.8.1

Can I please get link for this DS3231 Library that works? I tryed so many different libs, without any luck. Please Help :)

Nikola Nikolić hi , I have the same problem , tried many libraries ,can't find a solution , did you found something ? Tnx

+Frode Molland any arduino

Hi, great :) thanks for super fast reply, just started with arduino

+Frode Molland always here if you need help

thanks for info at this moment :) I have to order this matrix first, now I got the oled 0.96 inch screen and one lcd screen, but I want a bigger clock in my tv room :)

thanks

I tried this but still got this no matching function for call to 'DS3231::DS3231()' any help please

I've read through all the comments to see if I could fix the same problem. I've done all these suggested fixes but to no avail.

Thanks for any help. Tired of pulling my hair out.

The RTC module has a temp sensor on board

You are using a newer version of the library.

Yes

I don't know, I don't have a ds1307

learnelectronics Thanks . Nice day and project:) Clock.getTime (year, month, date, DoW, hour, minute, second); error: 'class DS3231' has no member named 'getTime' Pls You help me ?

yes

easy clock

oh com'on , he shouted "easy clock" more times than I paused the video, pay attention

They have updated the library and changed classes.

What does NCV mean?

learnelectronics No Se Ve (fonética NCV en español) ... Similar at 4U (for you in english).
