Twitter

Twitter is an online social networking service that enables users to send and read short 140-character messages called "tweets". Registered users can read and post tweets, but those who are unregistered can only read them. Wikipedia

Important Notes about Twitter!

  • Make sure your tweet is not the same to the previous one, have a minor difference e.g.
    • "01 Testing Tweet #IntelEdison #IAmIntel"
    • "02 Testing Tweet #IntelEdison #IAmIntel"
  • Make sure the time between tweets is within the limits

Grove Starter Kit Plus

Grove – Button

Author: Sarah Knepper [email protected] Copyright (c) 2014 Intel Corporation.

root@edison:~# vi button.py
import time
import pyupm_grove as grove

# Create the button object using GPIO pin 2
button = grove.GroveButton(2)

# Read the input and print, waiting one second between readings
while 1:
    print button.name(), ' value is ', button.value()
    time.sleep(1)

# Delete the button object
del button
root@edison:~# python button.py

Grove - LCD RGB Backlight

Author: Brendan Le Foll [email protected] Copyright (c) 2014 Intel Corporation.

root@edison:~# vi lcd.py
import pyupm_i2clcd as lcd

# Initialize Jhd1313m1 at 0x3E (LCD_ADDRESS) and 0x62 (RGB_ADDRESS) 
myLcd = lcd.Jhd1313m1(0, 0x3E, 0x62)

myLcd.setCursor(0,0)
# RGB Blue
#myLcd.setColor(53, 39, 249)

# RGB Red
myLcd.setColor(255, 0, 0)

while True:
    myLcd.write('Hello World')
    myLcd.setCursor(1,2)
    myLcd.write('Hello World')
root@edison:~# python lcd.py

Your Twitter Code

root@edison:~/myproject# nano twittersample.py
#!/usr/bin/python

import ConfigParser
import os

from twython import Twython

class xTwitter(object):

    def __init__(self):

        self.configuration = ConfigParser.ConfigParser()
        self.directorycurrent = os.path.dirname(os.path.realpath(__file__))
        self.configuration.read(self.directorycurrent + '/configuration/credentials.config')
        self.consumer_key = self.configuration.get('twitter','consumer_key')
        self.consumer_secret = self.configuration.get('twitter','consumer_secret')
        self.access_token = self.configuration.get('twitter','access_token')
        self.access_token_secret = self.configuration.get('twitter','access_token_secret')
        self.twythonid = Twython(self.consumer_key, \
                                 self.consumer_secret, \
                                 self.access_token, \
                                 self.access_token_secret)

    def tweet(self, status="", media=None):
        if media:
            photo = open(media,'rb')
            self.twythonid.update_status_with_media(media=photo, status=status)
        else:
            self.twythonid.update_status(status=status)

if __name__ == "__main__":

    idTwitter = xTwitter()
    idTwitter.tweet('#TheIoTLearningInitiative Testing Time')
root@edison:~# python twittersample.py

Look at your Twitter account...

Challenge

Create an application using Twitter, Button and LCD... Button can be used to push a tweet (Core library usage will be enough) and LCD can be used to display latest tweet (direct usage of Twython API is required)
