Hello , I am building a project I saw on YouTube. https://www.youtube.com/watch?v=mTdiO4Nka6o I know the LEDs are working because I used a different controller to test. When I download the code to the Arduino and connect it to the LED matrix as per scribe wiring diagram , the LEDs do not lite up. I tried two different Arduino nanos.
I am using a solderless breadboard for my testing Is it the code or h/w (Arduino)?
The project designer does not answer email. Also under Programming Questions there are several articles about the code. https://forum.arduino.cc/?topic=707456#msg4754605
I will be using this LED matrix for my Christmas Light show.
Thank you in Advance
