ShutdownButton
==============
This program provides a simple shutdown function of the Raspberry Pi.
Just connect a button to GPIO 25 and GND and press it to shutdown.
Optionally you can connect a status led to GPIO 24 to indicate if the program is running
and the button press was recognized.
Installation
============
In order to install the program so it runs at startup you need to [**install wiringPi**](https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/)
and create an entry to rc.local.
```bash
#copy program
$ sudo cp ./ShutdownButton /home/pi/Desktop/Programs/ShutdownButton
# set rights to execute the file
$ sudo chmod 0777 /home/pi/Desktop/Programs/ShutdownButton
# test program first
# abort with crtl + c
/home/pi/Desktop/Programs/ShutdownButton
# open autostart file
$ sudo nano /etc/rc.local
# add the script (above exit 0)
/home/pi/Desktop/Programs/ShutdownButton /dev/null 2>&1 &
# press ctrl + x and save with y
# reboot your system
# kill the Program
sudo killall ShutdownButton
```
Hardware Setup
