Hi Mike,
thanks for youre comment. I thought about that, but i saw a lot of tuto's on the internet that hasn't used them.
Look at this one: Experiments 5.3: 8x8 LED Dot Matrix Display Tutorial (Red/Green Common Anode) using the Arduino - YouTube
but when i do use one, wich is the best one to use?
by the way:
i did mention to get the 4 leds working now with two 74hc595's! FINALY..
What a great evening!!!
Now i'm going to replace the 8x8 matrix to test some things.
thanks.
