My First Raspberry Pi (RasPi) Post…GPIO

Reading and Writing to the RasPi GPIO using BASH

The top header is the gpio. It’s nice that it’s called the gPIo. How convenient!

I’ve finally taken some time to play with my Pi after getting some of the peripherals to work. I struggled getting the sound to work, but finally found a post that described what to do. I’d like to point out that I’m still using Debian Squeeze. That might be where some of my issues stem from.
