web-pins

This is a simple interface for reading and controlling the GPIO pins on the Raspberry Pi

There are a few steps needed.

Installation

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

git clone https://github.com/TheGreenToaster/web-pins.git

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

Usage

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.
