DEC #15 Arduino Digital Clock final built version 0.1

This is the follow up on my project to make Arduino digital clock. I have used MAX7219 for driving the 7 segment LED display units and Chronodot RTC module for real time clock sensor. It has a DS3231 IC in a breakout module. You may watch my previous video on interfacing each of these with arduino separately.

Nice project, well explained and presented. I wouldn't have the patience to wide it up on perfboard. I'd design a PCB.

[@davidkinuthia1052]

very cool project only two ics and its working all those 7segments..i will try out anyway thumbs up

[@skgonh08]

Whats the size of big leds ? Is it 0.56 inch or 1 inch or 2.3 inch

[@bazrazin1]

brilliant, you wrote the code yourself, i also made 3 clocks ds1307, st7789 tft lcd,16*2 lcd & common anode hand made 7 segment led's, mostly from other ytube vdos, but still struggling to make it into 12hr o/p studied the code several times but still unsuccessful.

Nice

When upgrade video coming on this we want more update clock with more function????

RTC_DS3231 library not matching with adafruit rtclib (DS3231)..... Sir, could you pls tell me the path of RTC_DS3231 LIBRARY? thanking you

[@altruf]

sketch for arduino at the link - does NOT match the diagram and this watch (sketch for using 74595, but not for MAX7219, which is a fundamental difference)

[@sonuala5671]

Sir pl make this in 12 hrs clock its awesome

[@sonuala5671]

Can I used big led 7 seven segment display?

[@sonuala5671]

Sir I have try to make this clock how to adjust the time and date ...pl guide

I have tried this but I'm getting error in rtc can u give link of rtc library plll

How to change this clock into ntp clock?

[@omorfaruk1]

Fine, Please tell me the segments are Common Anode or Common Cathode? and Code about CA or CC? Can I use DS3231 Regular Module here in stead of Chronodot ? can i change time to 12 Hour mode?

[@DigitalElectronicsCircuitsLab]

these are common cathode segments because Max7219 cannot drive common anode segments and hence the code is for Common cathode only.
Yes you may use any DS3231/DS3232 module or IC with this code.
If you want to make 12 hours clock then you have to add 3 lines of code.
