This Arduino project will display RSS feed headlines on an LCD via an Arduino and a USB cable. It works quite well, and lets you keep up with the world news while you're sitting at your desk. Many of the values in the code can be changed, and the system can be adapted to display Twitter and other information as well. It uses Python to interface with the Arduino.
All of the code and instruction provided is done so with no guarantee of success. I've bugtested the code to the best of my ability, and it should work in most cases, but certain things can throw it off. Details of such are within.
Step 1: Required Pieces/Parts for the Project
The project requires very few parts, generally things that most people with Arduinos will have lying around somewhere:
(1) Arduino Uno board
(1) Breadboard (I used a MakerShield prototyping shield instead, but a breadboard works just as well, albeit less compact)
(1) LED, your choice of color
(>12) Breadboard cables
(1) 16x2 Character LCD display, compatible with the LiquidCrystal library (works with larger LCD's with tweaking)
(1) Potentiometer, preferably 10K ohms.
(1) USB to USB-B cable (standard USB-to-Arduino cable)
