GPIO on Raspberry Pi
If you already have your hands on a Raspberry Pi and are eager to make some LEDs blink and read the status of pushbutton switches, I want to share with you this excellent tutorial by Tedb0t. He shows you the ins and outs (so to speak) of how to use the general purpose input/output (GPIO) pins on a Raspberry Pi board. He covers everything from physically connecting to the GPIO headers to accessing them within Python, Bash, and C. And to those of you who are still anxiously waiting to receive your boards, I know it’s rough, but at least you have some time to bone up on this while you wait.
