Raspberry Pi Pinout Official

Pin GPIO ( G eneral P urpose I nput O utput) of the Raspberry PI Pinout allow us to work with electronics easy way we could also do with Arduino .

There are 26 pins organized in two rows of 13, and each of the pins either has its specific function or is of general purpose, I am going to show the distribution of the pins of the Raspberry PI Rev 2.0 , since it is the one I have .

As we can see in the following comparative image of the two revisions, in the second revision of the IP we have two + 5V , five GROUND (ground), two + 3.3V , eight GPIO general purpose pins , five SP10 , two UART , and two I2C1 pins .

With them we can control electronic circuits , for example to move motors or control the on and off relays that will act as switches for 220V circuits .

These pins can be configured and controlled directly from the interpreter Bash , or from programming languages ​​such as C or Python , thanks to the GPIO libraries that have been implemented for them.

In my case I have chosen Python , because although I have never programmed in this language, what will allow me to learn on the go with you, is one of the recommended to start programming.

In addition I find very interesting the possibility of executing the Scripts in Python that we write using an HTML button , which when pressed executes a function in PHP , which in turn calls to execute the Script in Python.

Raspberry Pi 4 release date

This will allow us to manage our projects from the browser of any device through a Web application, so we can get to implement very economic domotic solutions , for example.

Now that we know are the pins GPIO and to serve in the next installment we will see a slight introduction to basic electronics to finally mount a circuit like the following scheme to light a LED diode and check that everything is ready and works correctly, to what I have called Hello World version GPIO

Raspberry Pi 4 is coming
