I am building a project I saw on YouTube. Smartphone Control RGB Scrolling Text Display LED Matrix - YouTube
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. Arduino Forum
I will be using this LED matrix for my Christmas Light show.
Thank you in Advance
