Yes, I've looked at the datasheet, but I don't know what 90% of the pin's labels mean.@ Joe That is really good, but on top of that, what other pins can I use as I/O? I need more then the arduino provides.Heres what I got now:1) Reset2-6) Digital I/O Pins7) Vcc (input voltage at 5 volts? Correct me if I'm wrong)
20) Vcc (More 5 voltage input?)21) analogue reference? What does that do? (I'll google it)23-28) Analogue input (they can be used as digital I/o, right?)
So that gives me 15 digital I/O pins (2-6, 11-19), and 6 Analogue inputs (I need 6 digital Inputs and one analogue)So what is another pin that I can use as an analogue input?
And how do I program what each in does? Do I just do it in the software, and say something like pinMode (23, INPUT); ?
Also, what cable do I need to connect it to the computer for programming?
