Hi, I am trying to build and LED wall and I want to control it with the Audrino Uno. I understand that you can connect up to 10 LEDs in parallel to the Uno, but I need to connect way more than that. Is there a tutorial on how to increase the amount of LEDs connected to the Uno?
How many LEDs do you want, and connected how? Blocks of 10 that turn on at once, 100 that are all individually controlled? Any thing is possible, some arrangements may take more hardware than others. For instance, you could use MAX7221 to control 64 LEDs, or use several of them to control 64 each. Or use a MAX6953 to control 4 blocks of 5x7 LEDs, or use several of them.
Provide more details for better suggestions.
OfCourse you can connect more than this number!!! Well.... you can connect De-multiplexer between Arduino and LEDs!! Even you can Control your any LED and can generate patterns.
Here is PDF for IC74154:
