This project is based on/inspired by the Instructables article by quartarian at http://www.instructables.com/id/Raspberry-Pi-Garage-Door-Opener. It provides you with a web interface to activate your garage door opener, with some added security.

Once you assemble the hardware as described in his article, simply follow these steps to install the software:

1. Update the package repositories

   `sudo apt-get update

2. Install mySQL server. This command will also install any missing prerequisites. Enter a root password when prompted. (Be sure to remember said root password. It's kind of important.)

   sudo apt-get install mysql-server --fix-missing

3. Install Apache2, PHP5, and the PHP module for Apache with the following command:

   sudo apt install apache2 php libapache2-mod-php wiringpi git screen -y

4. Execute the SQL setup script:

   sudo mysql -u root -p < setup.sql

5. Navigate to the web folder:

   cd /var/www/html

6. Download the files to a folder named garage (assuming you want to use your Pi for additional projects):

   sudo git clone https://github.com/JoshuaCarroll/Raspberry-Pi-Garage-Opener.git garage

7. Return to the dashboard site root.

   cd garage

You should now be in /var/www/html/garage

7. Update scripts to match your hardware. In the Instructables article the author used GPIO 7, however I was already using that port so I used GPIO 18. If you do not want to use GPIO 18, here are the files you'll need to update. Just type nano filename to edit these files.

   • garagerelay.sh
   • trigger.php

8. Run these commands to install the startup script:

   sudo cp garagerelay.sh /etc/init.d/garagerelay
   sudo chmod 777 /etc/init.d/garagerelay
   sudo update-rc.d -f garagerelay start 4
   

9. Copy and set permissions for the status file.

   cp status.txt /home/pi/status.txt
   chown www-data:www-data /home/pi/status.txt 
   chmod 777 /home/pi/status.txt
   

1. Find your Raspberry Pi's IP address:

   ifconfig

   The IP address will be on the second line just after inet addr:.

2. Enter this IP address into a browser followed by /garage. For example:

   http://192.168.1.4/garage

3. Close the garage. This project will try to keep up with, and display, the status of your garage door. But it's pretty dumb - it assumes that the door is closed on first use and simply alternates that value.

4. Try it out. If you have everything assembled correctly it should work like a champ.
