Using pi-control-service for GPIO #piday #raspberrypi @Raspberry_Pi

Thanks to Brian Hines for sending in his write up! View more here.

I’ve spent good bit of time over the last month experimenting with messaging queues as a way to remotely control the GPIO pins on a Raspberry Pi. It’s turned out to be a nice strategy, so I published a couple of Python libraries (Pi-Control-Service & Pi-Control-Client) to make it easy for others to use this approach as well. After sharing these libraries on a couple sites, it was brought to my attention that not every Raspberry Pi owner may be familiar with some of components I was using, like RabbitMQ. To help out, I’ve put together a small example explaining how to get started.
 

OBJECTIVE

We are going to remotely control a single LED connected to a GPIO pin on a Raspberry Pi. We will be able to turn it on and off, as well as read its current state at any given moment without being directly connected to the Raspberry Pi. The example may be a bit contrived, but once you see how easy it is you’ll come up with something more interesting to control than an LED.
 

SETUP

Before diving into the code, we need to get a few things setup:
