Very interesting and informative. As an experiment I tried to power my matrix with an external power supply (common ground) with a current limiting resistor but it just will not work. Any thoughts?
I explained the working of the code for this display in the link: mytectutor.com/max7219-led-matrix-interfacing-with-arduino/ . Try going through critically you will find a solution to the display orientation problem
Sir, i want to ask when we connect this led matrix to arduino and then we connect them both with PC to upload program, does the matrix LED turns on automatically or not. In my case, when I'm connecting both the module with PC, some part of the LED turns on and some are off. This is my first project and i have very basic knowledge about electronic and nil about coding.
Your video made that so easy. It worked perfectly first time. Thanks a lot!
fantastic video,very educational.thanks for sharing.

.. I tried it on a mega arduino and it doesn't work. Could it be that this parola library is only for arduino uno?
me to i have a uno
