Are Pin0 and Pin1 available to use as INPUTs?  Or are you only suppose to use those for Serial communication? XD

They are available as inputs if you are not using Serial. Be aware that whatever is connected to them can interfere with uploading sketches.

The analog pins can be used as digital pins, if they are not being used as analog pins.

And be aware that pin 0 will appear and operate as if it has an external 1K ohm pull-up resistor applied due to it's connection the the USB serial converter chip, even if serial commands are not being used.
