I am currently working on an LED 4x4 cube, so here is my pre planned circuit diagram.
I am to connect 220ohm to each positive terminals.(16)
I am to use 4 transistors(2n2222) for 4 negative layers of which, collector terminal will be connected to the negative terminal layers , base will be connected to 4 analog pins through 1k ohm.
Can I run them all together?
Is there any way to make it?
Explanation with circuit diagram will highly be preferred...
Thanks for your precious time...
