KA05 pins always HIGH

The digital pins 2-7 are always HIGH. Why is this or what could be causing this?

Digital inputs should be pulled to ground to activate them. Please try this.

What do you mean by pull to ground?

If I set 2 - 7 to output the green LEDs come on, even though I did not digitalWrite them to HIGH. They come on even when digitalWrite to low.

But they are inputs.
You should set the pins to inputs, then externally ground them to active the digital in.
