Multi Mode Digital Clock

- เผยแพร่เมื่อ 26 ก.ย. 2024
- This is an Arduino driven digital clock with 6 modes of displaying the time. Even temperature is displayed.
Hardware:
4 x cheap MAX7219 Dot Matrix Modules, 1 x DS18B20 temperature sensor, 1 x DS3231 realtime-clock and 1 x Arduino Nano.
For further information take a look at my (German) page at:
arduino.joergel...
I was actually redirected from Nick's page, as seen your improvised clock in the comment section. Thanks, you did a massive overhaul in the entire code with addition of great features. Especially liked the LDR brightness control and digital temperature sensor portions. After read your blog post, I finally made one, with standalone AVR (Atmega328PU) in a custom made PCB.
- Translated most of the German part as English, except the word clock portion. Seems, it uses different convention for representation than that of English.
- Removed DST code, since not used in my geographic location.
Thanks once again, for sharing your research work & code with us.
Thanks for your comment, enjoy your clock.

AWESOME PROJECT!!!i build one for my table clock using nano, also added some features such as EEPROM,ALARM function and DHT22 temp interface since i do not have ds18b20 sensor, big thankss!!!
เป็นโปรเจ็คที่ดีมาก ขอบมากเลย Good Project
Thank you

'class DateTime' has no member named 'dayOfWeek'; did you mean 'dayOfTheWeek'?
Hello, it shows me the temperature on the screen 4 times, I want it to only appear 1 time which line I have to modify.
Best clock ever seen on TH-cam, hatsoof
I wander if you may add alarm to it
you can add two alarm if you are using ds3231 , simply make an alarm function then add it to the void loop
works fine . the problem is its vertical clock how to make it horizontal???
Hi
I have ws2812b flexible rgb 8x32 dot matrix led panel. Can you make a clock video about it?
Hello. I have assembled this project, and the text inverted. I need to rotate the text 90 degrees counterclockwise. You could help me? thank you.
Hi,
please look at the comment from "The Hoss".
He had also a problem, but with 180 degrees rotated chars
He fixed it -> look at his modification-code.
Perhaps it also helps with your 90 degrees problem?
Jörg
@@jorgbaumann7123 Thanks for answering me. I made the suggestions of "The Hoss" and did not solve my problem. I also looked at various suggestions from others on the blog and also did not solve. I would like to send a photo of the display, to see if you could help me. My email is eudeciogs@hotmail.com. Thank you.
I solved the display problem. I changed the display order to 3.2,1,0 and changed the line lc.setLed (address, 7-y, x, true). Normalized, I will now see why the temperature is wrong is undercutting -127 ° C. I use the DS3231.
@@eudeciosilvaOficial
Hi,
glad to hear, that you solved it.
Problem occured, because there are different types of MAX72xxx-modules on the market.
When DS18B20 shows -127 degrees, will mean, there is a problem with the connection to sensor.
Please check your wiring to the sensor.
Jörg
I forgot to mention that I do not have the DS18B20 sensor, I'm only using the DS3231. I will study your program to change the temperature for this sensor, Eudecio.
Good clock
finally its working thanks kudos
Awesome project! Thank you so much... And whoever that use "FC16" hardware ; must change void plot function like this: ---
void plot (byte x, byte y, byte val) {
//select which matrix depending on the x coord
byte address;
if (x >= 0 && x = 8 && x = 16 && x = 24 && x
big thanks it help me out in my display since i am using fc16
@@marlonragusta3645 👍
Very cool! I read that the Matrix you are using are the Generic ones, so they are rotated 90 degrees!
Where should I change the code to use Matrix FC-16 (from ebay)? Thanks
Yes,
two buttons.
Take a look at arduino.joergeli.de/digiclock/digiclock.php, there you can see the circuit-plan.
100% Working.
I have 1 MAX7219 LED module (4 in One), it comes out at 90º, which line do I have to modify the set rotation so that it comes out horizontally, can you tell me please
Please look in the comments here from Eudacio Silva and/or The Hoss.
Hello, thank you Jörg Baumann and Eudèco Silva for sharing your information.
quick share: if you are using dht22//11 instead of ds18b20 add this in your sketch:
delete or comment first all ds18b20 related stuff
then add this:
#include "DHT.h"
#define DHTPIN 4 // connect any pin in arduino board you are using i am using d4
#define DHTTYPE DHT22
DHT dht(DHTPIN, DHTTYPE);
dht.begin(); //add this inside void setup
then find this function:
char measure_temp()
add this inside:
float TempC = dht.readTemperature(); //this is for dht22 ,old one is for ds18b20 sensor
replace the old value of float Tempc with new one
Hit compile if error occurs check if there are still ds18b20 stuff , comment them or delete!
thank me later...
Hi Jörg, danke für diese Super Uhr. Ich wollte sie jetzt mit 8 Displays betreiben (2x 4in1 MAX7219) bekomme es aber nicht zum laufen.
//sets the 3 pins as 12, 11 & 10 and then sets 4 displays (max is 8 displays)
LedControl lc = LedControl(12, 11, 10, 8);
Ich habe 8 für die Anzahl der Display's eingesetzt, aber die zusätzlichen 4 Display's zeigen nichts an. Muss ich noch etwas ändern damit es mit 8 Display's läuft ?
Hi Jörg, thanks for this great watch. I wanted to run it now with 8 displays (2x 4in1 MAX7219) but can't get it to work.
//sets the 3 pins as 12, 11 & 10 and then sets 4 displays (max is 8 displays)
LedControl lc = LedControl(12, 11, 10, 8);
I put 8 for the number of displays, but the additional 4 displays show nothing. Do I have to change something to make it work with 8 displays?
Sorry,
das mit "max is 8 displays" ist noch ein Überbleibsel aus meiner Testphase.
Somit nur 4 Displays, oder "works as designed" ;-)
Joergeli clock mirror image I did many changes but mirror display .pls tell me code changes
You probably are using other Matrix-Modules than mine.
Please read the comments here, where other users have similar problems ( rotated 90 degrees, rotated 180 degrees, etc.)
Perhaps the answer (and code) from The Hoss (2 years ago) can solve your problem?
Can help you to make the code with the sensor DHT22/11 Tanks.
I finish work many thanks ^^
You are welcome
90 degrees to 180 pls
I have a problem with the clock, it shows me an hour of +, I make the adjustment DS1307rtc set time, how can I solve it
In Germany we have daylight saving time at the moment, which means 1 hour is added.
If in your country there is no DST, remove the DST-code from the sketch.
@@jorgbaumann7123 Hi, I'm from Spain. It should work. Can you tell me which line I have to modify?
@@pascualpalacios7099
It's long ago, since I made the sketch ;-)
So I'm not shure, if this simple workaround works:
Replace all! the code from line 2415 to 2424:
// European Daylight Savings Time calculation by "jurs" for German Arduino Forum
// input parameters: "normal time" for year, month, day, hour and tzHours (0=UTC, 1=MEZ)
// return value: returns true during Daylight Saving Time, false otherwise
{
if (month10) return false; // keine Sommerzeit in Jan, Feb, Nov, Dez
if (month>3 && month=(1 + tzHours + 24*(31 - (5 * year /4 + 4) % 7)) || month==10 && (hour + 24 * day)
Hello, I have the same problem +1 HOUR...Did you resolve it?. How?..Thank you
how do you make it from scratch, it's very good,, let try bro
BUTTON_PULLUP WAS NOT DECLARED IN THIS SCOPE ===ERROR MASSAGES
Did you include Library from Alexander Brevig ? Attention: Case Sensitive
Do you have those 2 lines in the code (also Case Sensitive):

Hello Sir, it's a nice clock, I want to build like this one. When I compile the scratch it shows so many errors like this: 153 3: use of undeclared identifier "wire1", 165 18:use of undeclared identifier "intro", like this "small", "basic", word_clock ...
Please help me what can I do, I don't change your scratch.
Hi,
I do not know, what's going wrong, because many other had build this clock, without getting any errors while compiling the sketch.
Perhaps it depends of the Arduino-IDE, you are using. I compiled it with Arduino-IDE V 1.6.7.
Perhaps you did not download all the necessary libraries (Wire.zip, Rtclib.zip, etc.) and put them in the right folder?
@@jorgbaumann7123 Thanks bro. Finally I can make it. You are right when I use Arduino 1.6.5 it show no errors. But it is showing vertically. I can not make it 90° rotation by changing in Plot. I have seen your comments how to change in Plot.
@@azizulhaque7867
Hi,
look at the comments from Eudecio Silva, he had also a 90degree rotation problem.
He described his solution to fix it in his comments.
Perhaps this will also help you?

Hello, the temperature sensor DS18B20 could be changed by a DHT 22? Thank you.
Victor M. Estefano Defrias
Hi Victor,
I think it's possible to use the DHT22, because it uses only one pin at the arduino.
Of course you have to alter my sketch in the section "char measure_Temp()".
For example, a sketch for the DHT22 you can find at: fluuux.de/2012/10/arduino-temperatur-und-luftfeuchtigkeit-mit-dem-dht22-prufen/
@Ady Sos
Hi,
unfortunaly I don't have his sketch.
But surely you can find similar sketches on the internet.
Simply search for "arduino DHT22".

That was not my site, it was only an example, how to read the DHT22 with Arduino.

hi my friend :)
ı uploded your project but matrix wrong run. it looking vertical ?
Hi,
seems, you are using other matrixes than mine.
Take a look at

The problem of vertical/horizontal is addresed in the comments.
it gives error compiling board for arduino nan0
What errors?
Please describe errors, which occurs while compiling.
why is the clock upside down
Because you use other modules than mine.
Take a look at the other comments, where rotation problems (90degrees, 180 degrees, etc.) has been solved.
Where I can buy this clock? It's looking amazing by the way.

Sorry, but there is no shop where you can by the clock.
You can only do it yourself, if you are familar with Arduino.

I have a tried the nick's led code and its working, but I when I try your code the the matrix not display it properly, I change something in nicks code to work for me, so I do change in the plot section of you code, but still i get mirrors display, pls hlp, by the way I have the $ connected modules
Hi,
perhaps this problem occurs, because there are different matrix-modules available at the market?
In Nick's blog there is a notice about this:
This is most likely because you don’t have the exact matrix modules from IC Station. Other modules from eBay can be wired up differently, so the LED’s are in a different order. You can usually fix things by tinkering with the function “plot” in the code. Look for the comment “plot a point on the display” and the line starting “void plot”. Switch the x and y in the 2 lines that start ” lc.setLed(address, y, x, true ); and lc.setLed(address, y, x, false);”. This will plot the pixels 90 degrees around.
Jörg Baumann I make it work by just removing a line from plot, i have translated most of moth and days but 8 cant translate the word clock can you have eng version of code
Soumojit Ash
I'm sorry, I have no english version of the word-clock-mode, but I think, it's not so different to translate it in the sketch.
There are only some "words" in the code: F-NF = five, ZEHN = ten, VIERTEL = a quarter, VOR = before, NACH = past, HALB = half.
Jörg Baumann I will try to translate
@@soumojitash3972 Dear bro. I have same problem of 90° rotation. Can you tell me which line should be remove to correct it?
Hello after compiling me from 'BUTTON _PULLUP was not declared in this scope. What should I do? I installed all the libraries.
Hi,
do you really have included the button-library: #include ?
Attention: Case-Sensitive : button.h is not Button.h !
I had already installed Button by Adams Michael. Okay? I wait for an answer thanks.
@@federicoferrara125
Hmmm..., no one reported this problem before.
Perhaps it is because I use a button-library by Alexander Brevig (as added on my website)?
If you have not made any modifications to the sketch, unfortunal I have no further ideas, why it's not compiling well.
Sorry
Jörg
@@jorgbaumann7123 Now I delete the other Button libraries and insert the Alexander Breving one, in fact I ask you to send me the link to this library. Thanks, bye

Hallo Jörg, super Sache. Ich hatte auch das Problem, dass mit einer 8x32 Amazon Matrix alles durcheinander war. Ich hab gesehen, dass Du die Segmente um 180 Grad gedreht hast. Leider hatte ich Deine Webseite zu spät gefunden und den Code dahingehen geändert, dass ich die Segmente in umgekehrter Reihenfolge ansteuere. Somit musste ich die Matrix dann auch nicht auf den Kopf stellen :)
//select which matrix depending on the x coord
byte address;
if (x >= 0 && x = 8 && x = 16 && x = 24 && x
Hallo Hoss,
ja, es gibt einige, die die Uhr nachgebaut haben, sogar aus Indien und Vietnam :-)
Manchmal gab es ebenfalls Probleme mit der Darstellung.
Abhängig von den verwendeten Segmenten war die Darstellung mal um 90 Grad, mal um 180 Grad gedreht, oder sogar spiegelverkehrt.
Meistens konnten wir es über eine Anpassung des Sketches lösen, aber Du hast ja bereits selbst eine Lösung gefunden.
Gruß
Jörg
I like the clock😍 and I ask permission to use the program code,
If allowed, we will make a video to upload on TH-cam
Thank you....🙏
Greetings🤝from Indonesia🇮🇩
Of course you can use the code, therefore Inuploaded it😊
If you probably get trouble with the direction of the numbers (upside down, rotated 90 degree, etc.), look in the comments here, other guys have posted solutions for that.
It's because of the different LED-Modules, that are available.
Have fun

Hi,
First you can try to turn "debug" on (1). Then you can see the output in the Arduino serial console.
Have a look at "wochentag" and "Tag" x "in Woche" ( day in week).
Second: check, if you also translated char monthnames [12] [4] in subroutine void display_date ate () correct.
If that doen't help at all, load my original (german) sketch once again and check, if there day and week are displayed correct.
If so, something must be wrong with your translation to english.
