- raspberry pi rev b
- motion sensor: http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/555-28027-PIRSensor-v2.2.pdf
- custom built led board
- install raspian on memory card
- install wireless network device
- install apache
- install php
- install python
- python utilities
- boot the pi
sudo python the_brain.py- this runs continuously and manages Natalia's inputs
- this must be run as root ( using sudo ) so that the GPIO library can access the GPIO pins
- add notes about pulse widths
- what are the current limits ( currently 0 to 500, 0 is off, 500 is max )
- how are the limits determined
- leds_off turn leds on or off
- is_default use default settings
- is_fire use fire mode ( flickering fire effect )
- custom_red_pw custom red pulse width
- custom_green_pw custom green pulse width
- custom_blue_pw custom blue pulse width
- custom_white_pw custom white pulse width

- repo: https://github.com/metachris/RPIO
- install guide ( was missing a few things in docs )
- $ sudo apt-get update ( needed to update stuff )
- $ sudo apt-get install python-dev ( need the python dev package to run the setup.py file ... which compiles stuff )
- $ git clone https://github.com/metachris/RPIO.git
- $ cd RPIO
- $ sudo python setup.py install
- verified as working: tbj 10.05.13
- download and install: https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/
- operation
- man gpio
- couldn't get the software PWM working. I don't think the GPIO CLI utility has softPWM built in yet.
