Very nice! I want to try it ;) Can you please post the stl or ipt files? Thanks!

You will not have a problem, just connect the cables as the pinout label. About the setting of the time, you can use the software app for android or windows and update the clock via bluetooth. This is necessary in first time and when you will change the coin battery after some time. I will take a look of the DS3231 in my next project. Thanks

1) If the FC16 Module uses the MAX7219, yes you can use it without any changes2) As the DS3231 IC has a different pinout from the DS1307 IC, no you cant use it... it's in compatible with this pcb board.

I can drive up to maximum 10 displays

Nice project! Can I add it in my website? www.Ardumotive.comIt's an Arduino playground with a lot of DIY projects and tutorials!Thank you for the share of this guide!

Sorry but you can't use the SPI as a program method with this custom pcb board.

Thank you netzener!

Thank you very much for your comment! I really appreciate it!* Part list updated* About video, I will try to make a better one next time and I will follow your advice* I understand what you are telling me about easyeda and I will agree with you* About JLCPCB, I will disagree with you, the quality of my PCBs is very good * About connections, PCB layout has labels for all connection parts, plus CN1 (power).

Nice and cleaver project! Well done!

Yes you can use any Arduino board you want

Install libraries first if you use the Arduino IDE.

Download it from step 3.

Hi! I just upload an updated code, also check your power supply, I am using 5V-3A.

Great!

Yes! 10k!

Hey! Did you make it?

I want to help but I can't understand you. Could you please send me your message in English? Thank you.

Thank you! Yes but I will soon publish a better app in Android playstore

Yeah, that's true ;)

Thank you!

Thank you very much SteliosN2!

Sorry but as I know Apple devices can't use Bluetooth adapter for data transmission. But if you find any Apple application that can do this let me know. Thanks!

Thank you Swansong ;) I hope to see a photo from your own compass!

Android app now available for download: https://play.google.com/store/apps/details?id=com.bt.mivas.ardumotiveledmatrix

Great! Don't worry, at the setup, below the line 59 matrix.setPosition(9, 0, 0); // And the last display is at <3, 0>Enter the following:matrix.setRotation(0, 1);matrix.setRotation(1, 1);matrix.setRotation(2, 1);matrix.setRotation(3, 1);matrix.setRotation(4, 1);matrix.setRotation(5, 1);matrix.setRotation(6, 1);matrix.setRotation(7, 1);matrix.setRotation(8, 1);matrix.setRotation(9, 1);Rotation (the second tag) can be: * 0: no rotation * 1: 90 degrees clockwise * 2: 180 degrees * 3: 90 degrees counter clockwiseGood job!
