Setup

Download the script, then install the GPIO library:

sudo pip install rpi.gpio

Then write your own python script to define when you want your LED to illuminate. This script will be called with a five second delay each time. When your script returns 1, the LED will illuminate; when the script returns anything else, the light will turn off.

Finally, wire up the LED to pin 18 and ground. For you non-hardware types, here’s a quick explanation: connect the longer lead of the LED to GND, and the shorter lead to an empty space on your breadboard. Connect that shorter lead to a 220 Ohm or greater resistor, and connect the other end of the resistor to the pin on your breakout board that reads ‘#18’.

Usage

This script must be run as su, or the GPIO library won’t be able to access the hardware correctly. Usage is as follows:

sudo python statuspi.py <your script>

To do

• Gracefully closing the GPIO library

• Allowing the use of multiple scripts and multiple LEDs through a yaml

  config file

• Customizable repeat time for scripts
