###PiCTA

This project uses the Chicago Transit Authority API to track the next two bus arrivals outside my house. I made it because I'm always checking and rechecking this information on my phone. PiCTA only displays the predicitions I care about and updates them automatically without any interaction on my part.

Most of these components were sponsored by Newark / Element14 - thanks guys!

###Server/Kiosk Setup

1. sudo apt-get install iceweasel
2. sudo apt-get install apache2 -y
3. sudo apt-get install php5 libapache2-mod-php5 -y
4. cd /var/www
5. sudo chown pi: html
6. Replace the contents of /var/www on your RPi with the files from this repository
7. Navigate RPi browser to RPi IP (do not open local file directly)
8. Edit getxml.php and add your API key, route, and stop ID (see php file for links)
9. Edit style.css to add a custom font

###Next Steps

1. Sometimes the page tries to load before the server fires up. Hasn't happened lately, so I can't pin down the problem.
2. Would be fun to add more features, like maybe animated weather backgrounds and automatic startup based on day of week and time of day.
