ESP8266 Internet Clock 

Works with little effort in short time. Cool! Thanks for designing and sharing!

Have solved the Board Manager 2.6.3 compile issue with the updatetime() subcommand.. In the Define Vars section add the following line: int epoch; on the updatetime() function change the following line: long epoch = round( curEpoch + 3600 * ( utcOffset + summerTime ) + 86400L ) % 86400L; to the following: epoch = (long)round( curEpoch + 3600 * ( utcOffset + summerTime ) + 86400L ) % 86400L; This ino will now compile with the latest board manager for the ESP8266 and work as before.

Summarise all the errors and added my cosmetics changes: *[1] compiling error* _Wrong:_ long epoch = round( curEpoch + 3600 * ( utcOffset + summerTime ) + 86400L ) % 86400L; _Correct:_ long epoch = (long)round( curEpoch + 3600 * ( utcOffset + summerTime ) + 86400L ) % 86400L; *[2] Show/Hide the date display. Wished it was the same thick fonts as the clock. If anyone knows how, pls let me know.* _To show the date, remove the "//" for these 2 lines_ printStringWithShift(date.c_str(),40); delay(2000); *[3] Date change to short date.* _Long date: THU, 06 AUG 2020_ date = " "+line.substring(6, 22); _Short date: THU, 06 AUG_ date = " "+line.substring(6, 17); *[4] if you're using ICSTATION version of MAX7219 hardware (I am) then u have to change this in the file "max7219.h". Other versions of MAX7219 are FC16 and PAROLA. You will know which version you have when you experiment with the sample examples in MAX_PAROLA inside Arduino program.* _For ICSTATION hardware, inside "max7219.h"_ Change: #define ROTATE 90 To: #define ROTATE 270 *[5] There's 2 clock functions inside. showSimpleClock() is for 8x32 matrix, showAnimClock() is for 8x56 matrix while animating the seconds moving. Both will looked the same on 8x32 matrix coz the seconds got truncated.* *[6] Remove prefix "0" if hour's first digit is "0"* Change: showDigit(h/10, 0, dig6x8); To: if (h/10 > 0) showDigit(h/10, 0, dig6x8); *[7] Adjust LED intensity according to different times.* _// Adjusting LED intensity._ _// 12am to 6am, lowest intensity 0_ if ( (h == 0) || ((h >= 1) && (h =18) && (h = 13) && (h

Code has been updated to use NTP - link to code is in the description. Looking for further improvements: 1) set wifi credentials and utcOffset via WifiManager and set in EEPROM.

Sorry for the wait folks. Code for this is now linked in the vid description. The clock uses json calls to google to get it's time which is pretty accurate. I have 2 things I would like help on from the community: 1) change time source to be NTP derived, and 2) implement the WiFiManager library so wifi credentials do not have to be stored. I didn't have time to implement those 2 things when I built/published this, but perhaps we could work together?

Cool idea! (the clock), but also it's funny that i thought a while ago the same as you, about doing something like that to piss off annoying drivers , they would freak out reading things directed specifically to them :p

UPDATE: link to code in description. Just pushed the latest commit today and here are new features: No more hard coding wifi creds or timezone! You can now flash to your favorite ESP8266 board, and setup is done via WifiManager! Set Wifi and Timezone UTC offset via any wifi capable mobile device! Whole and partial hour timezones are supported!

to show scroll date, uncomment lines 80,81 Line 64 setup your timezone

Something to improve next.... I setup a wireless hotspot but turn OFF the internet access. Power up the clock, clock starts up, gets connected but starts time at 8:00. It should have shown a get time error coz e.g power trip will cause the time to be wrong.

Thanks for the nice video. Had a spare NodeMCU and a MAX7219 laying around, this will make a cool deskclock. Now I need to print a case..

I liked the Clock, but the following is happening: Often, instead of the fourth digit, that is, the second digit of the seconds, it shows a completely filled square. Could it be a matter of food? Well, I'm feeding the Display Matrix through Nodemcu and this is connected to the PC's usb port.

Hello author, I thank you👍 very much for sharing your great clock, I have made one, in the code I will change it to Taiwan time

fonts problem , code not compile stacked in this line #include "fonts.h", error Arduino: 1.8.12 (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200" ESP8266-8x32-Matrix-clock:19:19: fatal error: fonts.h: No such file or directory #include "fonts.h" ^ compilation terminated. exit status 1 fonts.h: No such file or directory Board at COM3 is not available This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Can you tell me what needs to be changed or added to the sketch in order to register two access points (that is, two WiFi networks)? If one doesn 't work , will it connect to the other by itself ?

Hmm got it running now, but its wrong with many hours :) does have to stay on for a while to update?

Working good with nodeMCU v3, thank You.

Hello, can you modify the code to add the ds18b20 sensor to show the temperature?

great work, share the code please

Great project 🤝🤝🤝 How we can set india time accurately?

Is it enough current to supply to matrix module when use usb with power source ?

Very nice. Would you be able to share a link for the display, please? Also interested to see the source - did you find a library to render the graphics with scrolling, or write it yourself?

Great project, how many times does it fetch time from the internet ?.

the best clock !!!

The time is correct but date is one day ahead, how can we fix this? Thanks!

Would it still work, if I daisy chain another 4 matrix in?

Sir clock is working fine but date and day must change at midnight 12.00 but it changing at morning 5.30am resolve

Can you do tutorial pls? I have problem with library and program at all

very interested in code, very nice work

Hi friend, thank you for sharing. I downloaded your project but here is not happening the date Do you know what it can be?

Hello how to set 12hrs

code link in the description is not working, Kindly share the code via mail or by any other link. Thank you

hi there, you have any code for the ws2812?

broken link. please update it.

Great time piece, Can I view the code please?

I have this problem that the actual time is 04:02 and in the matrix it shows 204 and the last digit to the right is missing ( so it is mixed numbers places and one digit is missing ) any ideas about the cause and how to fix it (any volunteers) , thanks

Thank you

long epoch = round(curEpoch + 3600 * (utcOffset+summerTime) + 86400L) % 86400L; exit status 1 invalid operands of types 'double' and 'long int' to binary 'operator%'

Fajny zegar. Dziękuje za polskie znaki.

Would really like to see the code.

Please send code sir

Thank you so much..

could you change the URL to HTTP and not HTTPS, your sever doesn't support it

ciao john, come faccio a visualizzare il fuso orario dell'italia? grazie mille

Please share code and where you got the display.

cant download that code.its not working

can you describe the pins ? Please.

Can you add dht22 sensor in code please 😊

Hi John, looks like your file server isn't working again. Can you please repost your code? Thanks.

link broken, could you update?

Very nice project i made the clock and working fine the only thing date month and year is not showing please let me how to put the code for date month and year thanks Gur

verry nice, // better ?? #define DIN_PIN 13 // D7 - FIX #define CS_PIN 12 // D6 #define CLK_PIN 14 // D5 - FIX

can i have the code plz

Cant download that code not working thanks.

Error fonts.h Sir !

still not able to get the code....

How can you change time zone, I got this working but it is 4 hours ahead!

nice ....

Saludos desde Colombia.Me puedes dar el codigo por favor

Code ? Link Broken ...
