This pack includes the following components:



Tutorial

In this tutorial, we are going to explain how to use Python to do the experiments:

Environment Setup

Now we will install python-pip (pip is a package used to install and manage python software package, and it is used replace esay_install):

sudo apt-get install python-imaging python-imaging-tk python-pip python-dev git

Next, we will install spidev using pip:

sudo pip install spidev

Then we will install WiringPi (the driver for IOs on Raspberry pi, that can be used in C, shell script or Python, etc):

sudo pip install wiringpi

Linker Button

Connect linker_led to pin 27 of RPI, connect linker_button to pin 23 of RPI


Python code:

<syntaxhighlight lang="c">

import RPi.GPIO as GPIO

led_pin = 27 button_pin = 23

GPIO.setmode( GPIO.BCM ) GPIO.setup( led_pin,GPIO.OUT ) GPIO.setup( button_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

print ("\nlinker_led pin 27 , linker_button pin 23\n")

while True: if GPIO.input(button_pin): GPIO.output(led_pin,True) else : GPIO.output(led_pin,False) </syntaxhighlight>

Linker LED

Connect linker led to pin 27 of RPI.


<syntaxhighlight lang="c">

import RPi.GPIO as GPIO import time

led_pin = 27

GPIO.setmode(GPIO.BCM) GPIO.setup(led_pin,GPIO.OUT)

print "\nlinker led pin 27\n"

while True:

GPIO.output(led_pin,True) time.sleep(0.5) GPIO.output(led_pin,False) time.sleep(0.5) </syntaxhighlight lang="c">
