About the Raspberry Pi
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a
computer monitor or TV, and uses a standard keyboard and mouse. It is a
capable little device that enables people of all ages to explore computing, and
to learn how to program in languages like Scratch and Python. It’s capable of
doing everything you’d expect a desktop computer to do, from browsing the
internet and playing high-definition video, to making spreadsheets, word-
processing, and playing games.
What’s more, the Raspberry Pi has the ability to interact with the outside world,
and has been used in a wide array of digital maker projects, from music
machines and parent detectors to weather stations and tweeting birdhouses
with infra-red cameras. We want to see the Raspberry Pi being used by kids all
over the world to learn to program and understand how computers work.

Raspberry Pi Pin Numbering Introduction
There are three methods for numbering Raspberry Pi’s GPIO:
1. Numbering according to the physical location of the pins, from left to right,
top to bottom –the left is odd and the right is even.
2. Numbering according the GPIO registers of BCM2835/2836/2837 SOC.
3. Numbering according the GPIO library wiringPi.

Raspberry Pi GPIO Library Introduction
Currently, there are two major GPIO libraries for Raspberry Pi: RPi.GPIO and
wiringPi.
RPi.GPIO:
RPi.GPIO is a python module to control Raspberry Pi GPIO channels. For more
information, please visit:
https://pypi.python.org/pypi/RPi.GPIO/
For examples and documentation:
http://sourceforge.net/p/raspberry-gpio-python/wiki/Home/
The RPi.GPIO module is pre-installed in the official Raspbian operating system,
thus you can use it directly.
wiringPi:
The wiringPi is a GPIO access library written in C language for BCM2835/6/7
SOC used in the Raspberry Pi. It’s released under the GNU LGPLv3 license and
usable from C and C++ and many other languages with suitable wrappers. It’s
designed familiar to people who have practiced the wiring system in the
Arduino software.
For more information about wiringPi, please visit: http://wiringpi.com/
Install wiringPi:
Step 1: Get the source code
$ sudo git clone git://git.drogon.net/wiringPi
Step 2: Compile and install
$ cd wiringPi
$ git pull origin
$ sudo ./build
Press Enter and the script build will automatically compile wiringPi source
code and then install it to the Raspberry Pi.

Next, verify whether the wiringPi is installed successfully or not:
wiringPi includes a command-line utility gpio which can be used to program
and set up the GPIO pins. You can use it to read and write the pins or even
control them from shell scripts.
You can verify whether the wiringPi is installed successfully or not by the
following commands:
$ sudo gpio -v
$ sudo gpio readall
If the information above is shown, it indicates that the wiringPi has been
installed successfully.

How to Use wiringPi and RPi.GPIO
For how to use the wiringPi C library and RPi.GPIO Python module, here we
take blinking an LED for example.
Step 1: Build the circuit according to the following schematic diagram
For Python users:
Step 2: Create a file named led.py
$ sudo touch led.py

Step 3: Open the file led.py with vim or nano
$ sudo vim led.py
Write the following source code, then save and exit.
Step 4: Run
$ sudo python led.py
Now you should see the LED blinking. Press ‘Ctrl+C’and the program
execution will be terminated.
For C language users:
Step 2: Create a file named led.c

$ sudo touch led.c
Step 3: Open the file led.c with vim or nano
$ sudo vim led.c
Write the following source code, then save and exit.
Step 4: Compile the code
$ sudo gcc led.c -lwiringPi
After the command is executed, you'll find a file named a.out appear in the
current directory. It is an executable program.
Step 5: Run

$ sudo ./a.out
Now you should see that the LED is blinking. Press ‘Ctrl+C’and the program
execution will be terminated.

Before you continue learning, please copy the source code provided with the
kit to your Raspberry Pi's /home/ directory, or download the source code
directly from our github repository:

Step 4: Run
$ sudo ./led
For Python users:
Step 2: Edit and save the code with vim or nano.
(code path: /home/Adeept_Sensor_Kit_for_RPi_Python_Code/01_LED/blinkingLed_1.py)
Step 3: Run
$ sudo python blinkingLed_1.py
Now you can see the LED blinking.
