Here’s a Raspberry Pi hack that adds web control using PHP and MySQL. As you can see in the image, it serves up a webpage (using the Apache2 server) which allows you to change the state of th… ...

The GPIO pins on the Raspi are arranged in a 2×13 header. Until Sparkfun manages to manufacture a decent Raspi protoboard, the easiest way to break these pins out is with an old IDE ribbon cable.

One of the biggest draws of the Raspberry Pi family of single board computers or SBCs is their expandability. That comes via the standard 40-pin GPIO header on the full-sized boards.

The Raspberry Pi Opto-pi board has been created to make interfacing with the 8 digital GPIO pins on the Raspberry Pi mini PC much easier. Allowing you to connect higher current devices as well as ...

Well, I figured it was about time to take a look at the Raspberry Pi. It's ... the GPIO layout changed between v1 and v2 of the Pi so ... an issue just need access to the GPIO pins. ...

For the Tx, with the pins facing you, attach the Raspberry Pi GPIO 0 to the leftmost pin, 5V to the middle, and ground to the right pin. Ground and 5V are from the Raspberry Pi, and the pins may ...

Two 5v pins are powered directly from the Pi's power supply, and two 3.3v pins are regulated down to this common voltage, leaving you with 31 unique pins and 28 true GPIO pins.

The Raspberry Pi board has a 40-pin GPIO header on it that needs through-hole soldering, along with bits like the Ethernet and USB ports. These require robust solder joints, ...
