Jeremy over at tuts+ posted this useful tutorial on building a tweet controlled RGB LCD screen with your pi.
In this tutorial I’ll show you how to use a Raspberry Pi with an RGB LCD to monitor tweets. Tweets containing specific keywords are displayed in defined colours. You’ll learn how to create a Twitter application to use the stream API to push data to your program, giving you an opportunity to learn about multi-threaded Python programs.
- Raspberry Pi model B ($40)
- Wired or Wireless Internet connection
- Adafruit RGB Negative 16×2 LCD+Keypad Kit for Raspberry Pi ($25)
- Follow the steps on the Adafruit site for setting up and testing your RGB LCD.
- Install Tweepy like so:
sudo pip install tweepy
Create a Twitter Application
Create a Twitter Application, on the Twitter web site, to allow the Raspberry Pi program to connect to the stream. To do this navigate to https://apps.twitter.com and sign in.
Create an application by completing the form, as shown below. Note: you can put a placeholder for the website–it’s a required field but not required for this Raspberry Pi project.
