Raspberry PI – Implementing an affordable home automation system [Part III]

After several months, I have decided to return to This project with which I intend to create a free home automation system, and economically affordable; This low microcomputer-based consumption, but cross-platform and portable to any device with OS GNU/Linux available from port GPIO.In previous posts We learned to control modules of relays optoacoplados with Raspberry PI by bash, PHP, and Python; on this occasion I have optimized the automation system, and incidentally I've migrated it to Raspberry PI 3 to dispose of wireless connectivity, But if you wish you can use any previous model.

Raspberry PI - implementing an affordable home automation system [Part I]

In previous posts in this series, We saw What are the GPIO pins, and how to control a LED with them from our Raspberry PI by Bash and Python, o with one web application.


On this occasion we will learn to control the power of an electrical appliance; before you start the server we have installed LAMP as we saw in the previous delivery.

Raspberry PI and GPIO pins: Controlling a LED with Bash and Python

In the previous post we saw were the GPIO pins and some examples of practical applications, Today we will focus on the operation of general-purpose pins, and learn to control them with the interpreter's orders Bash and with Python.


Will use a LED, a resistance of 330 ohm, wire, and one Breadboard, or solder and a soldering iron.

We will also need our Raspberry have already Raspbian pre-installed, If your case is not, You can see how to do it in the following link from the Directory.
