ESP8266 / ESP32 Clock

[@BudiYANZ-tc5fz]

Saya mencoba membuat jam digital ini, tapi kenapa waktunya tidak bisa sinkron dengan waktu di negara kami(indonesia) , code yang mana yang harus dimodifikasi ?

[@squalazzo]

good, but why ds3231 if esp* can sync time via internet?

[@cine-lights]

The ESP8266 is an older version and uses the DS3231, which to be honest i much prefer. the ESP32 uses the internet and syncs with the net. i also built a youtube subscriber display using the esp32 and it tends to drop out and loses its data. At least if you lose wifi the ds3231 will carry on supplying the time. i am sure there are other reasons.. But thats is the way schreibfaul1 designed it.

[@azzattar8422]

Excellent travail,bravo.

[@chulmin6082]

This code has to be rewritten twice per year . Because it is summer-time . Is there any one can solve this problem ? I mean with only one time uploading,

[@wibbley1]

Only three years for a reply, but the answer is yes. The ESP32 has an on-board real time clock. It will accept a code string, to set it to your local time and will then also adjust for summer/winter time. Easy to do, send me a DM if you want the details.

Hi This 12hr format available?

[@sk8t3rcz]

Hello, please is there any version of these clocks with temperature and humidity sensors? For example with DHT11/22 :) it could be cool. Thanks for great job!

[@Dancopymus]

I would like an answer on two questions: 1) In Brazil there is no summer time anymore. So, I would like to know which lines in ESP8266 to disable it. 2) How to add the OTA function to the code with ESP8266. Thanks

[@chulmin6082]

Read coding line # 278, 279 carefully !!!

[@Dancopymus]

​@@chulmin6082 Hi Chul Min, thanks for the reply but, I don't understand why line 279 "// epoch = epoch-3600 * 6; // difference -6h = -6 * 3600 sec)" in the ESP8266 code is commented on? If this line is uncommented, then should line 278 be commented out? Note that I need to disable daylight saving time completely (no longer exists in Brazil); thank you again

[@chulmin6082]

@@Dancopymus Line # 278 is actuale sentence. Forget it about daylight saving time . You can adjust your display time using Line # 278 . For example , your display time is 5 hours faster than real time , debug the Line # 278 like that " epoch = secsSince1900 - seventyYears -3600*5 +2; " . I hope your good luck .

you can make everything, but surely not with this code, there is a plenty of video on youtube about ws2812b clock, have a good day

Great Job,,,, is it possible to setup the wifi credentials (SSID and PW) not in Arduino IDE ?... maybe via Bluetooth with an app

[@cesarsilvanoesilvia2225]

Muito bom, Parabéns.

[@chulmin6082]

Serial.println(String(WiFi.localIP())); this column makes compile error, and someone had same question, in here you gave the answer, likes "Serial.println(String(WiFi.localIP());", but it was not right solution, still it can't go to next step. makes compile error too, What can I do ?

[@burapat4100]

sir, how to set the clock, the clock results are not right

[@chulmin6082]

Do you mean real time & led matrix display are not same ? You can't set up clock, clock signal is came from NTP through wifi. So we have to find coding to set up the time zone where you are located.

[@burapat4100]

@@chulmin6082 I am from Indonesia, can you help me how to enter the zone ... thanks

[@chulmin6082]

@@burapat4100 Firstable you have to know your location's longitude. Divide your location's longitude by 15 , first number is your time zone. For example Seoul's longitude is about 127.xx.xx. So 120~135 degree is time zone 9.

Hello, the author of this super clock I have one problem, I get an error with the IP address: although I gave the name of the network and password and the problem is with IP if you could help me thank you Roman

Do it works with 4 panels and can i display the time of diffrent contrys?

[@gusmilco8]

How if i would to change with indonesian time , can you tell us?

[@chulmin6082]

How many hours different to real time ? For example if it has 5 hrs difference , debug likes this, code line #278 , +3600*5. 3600 meas 1 hour's secound .

maybe do some search around DS3231 "Long number format: "

how to seting Serial.println(String(WiFi.localIP()));...........thnks

[@dtasim]

change to this Serial.println(String(WiFi.localIP());

That sentence might be compile error. Erase that one and put on likes " Serial.print("your network SSID"); Serial.println(WiFi.localIP());

This project should be getting real time data from NTP through wifi . I don't know why need the DS3231 RTC module . If someone knows this module 's function , Please leave the message to here for me !!!

[@cine-lights]

Hi agreed. It would be a great design, and then the DS3231 would not be needed. All the countries time zones would also have to taken into account. But its not designed that way. Its designed with the DS3231, I'm guessing temp may have been an option at the time using the inboad temp chip. But it didn't get that far You are more than welcome to design a clock and share it with us.

Brightness , it doesn't change by debugging with code . You may connect cds and 10 k ohm resistor to ESP8266 board.
