Best digital clock that you can made at home with arduino. All you need is 4 in 1 led dot matrix 8x8 pixels,RTC DS3231 and arduino board,for more info and downloads check :github.com/leo...
@Hacktuber Please I Need Help. I Have Tried To Make It. All Work Fine But My DS3231 Doesn't Set Time. I Also Tried another One But It Also Did Not Set Time. Please Help Me. The Time It Shows Is 1.1.2000 And Time Is 0:0:00
@@Hacktuber dear I was wrong .. the clock isn't steady.. stops scrolling suddenly, or runs fast, becomes unable to read . Resets automaticaly to either old date or advance date like 2031 randomly.. the Arduino blinks in between and resets all.. changed Arduino, rtc n battery too.. no luck.. what could be possible reason or it's the max7219 is culprit?
@@Hacktuber dear, I had an old arduino Uno R3, which I replaced with Uno, even the Uno too was troubling but Uno R3 is seems good so far. No friezing no resetting , not scrolling rapidly so far..seems , in mine case I must use Uno R3 instead of Uno and Nano..so far so good..
Good one !!!! Followed all the steps.. uploaded the given code to Arduino.. no luck.. Clock doesn't show any sign of life... One question have u used Arduino Uno or the nano ?
Este programa me funcionó correctamente sin problemas lo recomiendo gracias al creador y a la persona detrás de este vídeo también le agradezco la verdad trate con muchos programas y todos tenían detalles y no me funcionaban
You have to remove the Resistor that is above the SCL line and goes to the Diode on the RTC module! This module was made for a rechargeable coin battery. Removing either the Resistor or the Diode, prevents sending a charging voltage to the battery that will destroy it and may case other problems if you are using a normal CR2032 battery.
Great work and Thank You for sharing ... I try to follow you project for a dining room clock but I have a Problem with your Code : - I get an error : ////////// error: no matching function for call to 'DS3231::DS3231(const uint8_t&, const uint8_t&)' DS3231 rtc(SDA, SCL); ////////// I get this error NO matter what "sketch" I was using from internet ... Please can You provide a Link with the SPECIFIC library You used ? ... otherwise no use !!! THANK You
Upload the code to Arduino then go to serial monitor. Select same board rate as described in void setup. Then you see the date time setting process just send the date time as command and done
