These pin numbers follow the lower-level numbering system defined by the Raspberry Pi's Broadcom-chip brain.

GPIO.BCM - Broadcom chip-specific pin numbers.

The pin numbers follow the pin numbers on header P1.

Pin Numbering DeclarationĪfter you've included the RPi.GPIO module, the next step is to determine which of the two pin-numbering schemes you want to use: That statement 'includes' the RPi.GPIO module, and goes a step further by providing a local name - GPIO - which we'll call to reference the module from here on. In order to us RPi.GPIO throughout the rest of your Python script, you need to put this statement at the top of your file: language:Python On this page we'll provide an overview of the basic function calls you can make using this module.

This set of Python files and source is included with Raspbian, so assuming you're running that most popular Linux distribution, you don't need to download anything to get started. We'll use the RPi.GPIO module as the driving force behind our Python examples. This table shows the Pi pin header numbers, element14 given names, wiringPi numbers, Python numbers, and related silkscreen on the wedge. These are very handy when you're interfacing buttons with the little computer.Ĭheck out our Raspberry Pi video tutorials if you want a more visual introduction to the Pi!

Pull-Up Resistors - The Pi has internal pull-up (and pull-down) resistors.

Switch Basics - And to test inputs to the Pi, we'll be using buttons and switches.

Light-Emitting Diodes (LEDs) - To test the output capabilities of the Pi, we'll be driving a lot of LEDs.Pulse-Width Modulation - You can use PWM to dim LEDs or send signals to servo motors.Other, more general purpose tutorials you might be interested in reading include: If you don't have Raspbian set up, check out our Setting Up Raspbian tutorial before continuing down this rabbit hole. Raspbian is the most popular, well-supported Linux distribution available for the Pi. This tutorial will assume you have Raspbian installed on your Raspberry Pi.

Of course, feel free to swap in your preferred button and LEDs.

If you want to skip the breakout, you can instead use Male-to-Female jumpers to connect from Pi to breadboard.

The Pi Wedge isn't quite required, but it does make life a lot easier.

You can use either Ethernet or WiFi (check out our Raspberry Pi WiFi tutorial for help with that.

Your Pi will need an Internet connection to download WiringPi.

We're also assuming you have the necessary mouse, keyboard and display hooked up to your Pi.

Check out our How to Install Raspbian tutorial for help with that. Your Raspberry Pi should have an SD card with Raspbian installed on it.Some further notes on that bill of materials: Here's a wishlist-full of everything we used for this tutorial. C is faster and may be easier for those familiar with the old standby. Python is easy (especially if your a programming novice) and doesn't require any compilation. Our favorite IDE for programming on the Raspberry Pi.Įach programming language has it's share of pros and cons. Using an IDE - How to download and install Geany.WiringPi Example - A simple example program that shows off WiringPi's input and output capabilities.WiringPi API - An overview of the basic functions provided by the WiringPi library.

WiringPi Setup and Test - How to install WiringPi and then take it for a test drive on the command line.RPi.GPIO Example - An example Python script that shows off both input and output functionality.RPi.GPIO API - An overview of the Python functions you can use to drive GPIO.GPIO Pinout - An overview of the Pi's GPIO header.Here's a quick overview of what's covered: In this tutorial we'll show two different approaches to reading and driving the Raspberry Pi's GPIO pins: python and C. Whether you're a fan of the easily-readable, interpretive scripting language Python or more of a die-hard C programmer, you'll find a programming option that suits our needs. If you've never driven an LED or read in a button press using the Raspberry Pi, this tutorial should help to get you started. We've pared that list down, and ended up with two really solid, easy tools for driving I/O: Python and C (using the WiringPi library). Programming in what language? Take your pick! A quick glance at the Raspberry Pi GPIO examples shows that there are dozens of programming-language-choices. Driving the Raspberry Pi's I/O lines requires a bit of programming.
