Hi everyone, Im not sure whether my problem is hardware or software. Im following the "beginning arduino" book and am trying to do project 19. I have wired my led dot matrix specifically to the one i have, and I am confident that each pin connected from the 74HC595 IC's are connected to the correct rows and columns. (I disconnected the connection from each pin to see that the rows and columns stop lighting). I also had to include the TimerOne library and everything compiled correctly with the code from the book. All that happend however is all the LEDs light up, whereas there should be an image of a heart.
I have checked my wiring a billion times, every connection looks good. Im happy to upload a picture but the wiring is messy...I was wondering if anyone knew what the problem was just by my description. Let me know if you want any more description, picture etc if that would help. Thanks!
