rtc 1302 with 2 8x8 led matrices on: January 18, 2021, 03:08:13 AM
Hi, im new at this forum and new using arduino, i'm want to do a clock using a rtc module and 2 8x8 led matrices the problem is that the rtc i'm using is the ds1302 and it doesn't have that much tutorials or libraries, and i've been trying a lot of times to make it work but i still can't, i've downloaded around 8 libraries already and neither of those have worked yet, i just want to display the hour in those 2 led matrices by grabbing the data from the rtc module, both the rtc module and the led matrices work properely, but i just haven't been able to combine them for get what i want, i've been trying for a lot of time and still not.

rtclib i'm using--> https://github.com/msparks/arduino-ds1302
led matrix lib --> https://mega.nz/#!f2x0FKzR!jydqZCEr9X_R5XOqrm0R65V5fkai8YCP-lnzXjobSww

I'm trying to use the rtc values as a string for print them with that led matrix library, i took the code from this engenieer and tried to adapt it for my necesity but i couldn't (https://create.arduino.cc/editor/ProfeGarcia/71636291-66cb-46fb-af5d-d1d6d32ad9cd/preview). I placed my poor try of code if its helpful, at least it can make you laugh :/

If someone can help me by telling me how to combine this 2 libraries together it would be more than awesome, btw i'm sorry if this is not in the right place of the forum, i'm still a noob!

To display the time on two 8x8 LED matrices using data from the RTC DS1302 module, you need to combine them using an Arduino. To help you, you can try following these steps:

Connect the RTC DS1302 module and two 8x8 LED matrices to the Arduino according to the correct connection pins.
Use the library for the DS1302 RTC module to read the time from the RTC module.
Use the library for 8x8 LED matrix to display the time on the LED matrix.
If you have difficulty combining them, you may need to create a custom Arduino program to read the time from the RTC module and display it onto the LED matrix. These may require knowledge of Arduino programming and data processing.

Try time calculator to manage your time efficiently.
