Question about input pins.

What is the natural state of digital input pins on the RC. My mind tells me low, some documentation says high, and some other CD users say low.

Each digital I/O has a light pull-up to Vcc. So without anything driving the pin, you'll read a logic 1. It's documented here.

If you don't trust their answers, just take a multimeter to it... is it 5v or 0?
