This is a simple interface for reading and controlling the GPIO pins on the Raspberry Pi
There are a few steps needed.
Install LAMP
sudo su
apt-get update && apt-get upgrade
apt-get install apache2 php5 mysql-client mysql-server tomcat6 vsftpd
cd /var/www
Install GPIO Python library
wget http://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.1.0.tar.gz
tar zxf RPi.GPIO-0.1.0.tar.gz
cd RPi.GPIO-0.1.0
sudo python setup.py install
While in the www directory clone the web-pins folder
In order to allow the PHP to use the Python scripts the PHP user needs to be added to the sudoers file.
To enter the sudoers file use the command
sudo visudo
Next add the fallowing line to the end of the file and save it
www-data ALL=(ALL) NOPASSWD: ALL
In order to read the 0 pin the url is.
raspberrypiaddress/pi-read.php?pin=0
Simply replace the "0" with and number 0-7 to read that pin.
In order to set the value of pin 0 to high the url is.
raspberrypiaddress/pi-write.php?io=1&pin=0
To set value to low change
io=1
to
io=0
The "raspberrypiaddress"should be changed to the IP address of your pi.
