Getting python to interact with the real world(robotics/physical computing) - bsdpunk - 10-21-2009
As always this is brought to you by my blog http://bsdpunk.blogspot.com

For hardware you will need an arduino:
http://www.arduino.cc/
Arduino's are fairly cheap for getting into robotics/physical computing, you could spend as little as 20 dollars.
You need pygame and the python firmata installed. If you are on a yum based system you can install pygame by doing a:
yum -y install pygame
To install python firmata you will have to download it, untar it. Navigate to to directory in the terminal and then run this as root(or with the sudo command first):
python setup.py install
or
sudo python setup.py install
If you can't run them as root run each one with sudo in front of it:
PHP Code:
yum -y install git
git clone http://github.com/lupeke/python-firmata.git
cd python-firmata
python setup.py install
PHP Code:
sudo yum -y install git
sudo git clone http://github.com/lupeke/python-firmata.git
cd python-firmata
sudo python setup.py install
It is located here:

Your biggest challenge, may be getting everything installed, from there it should be pretty easy.
This is how to get started, with python and your arduino, bringing up the beginning of a GUI. It's just a taste of what you can do and I hope to go further on the subject. You need pygame, and the python firmata installed(explained here), and your arduino must have the firmata software on it as explained here. Here is the code I stole/wrote for getting the arduino to blink when you click within pygame. This outline should get you started with fun stuff:
#! /usr/bin/env python
import pygame
from firmata import *
proArduino = Arduino('/dev/ttyUSB0')
proArduino.pin_mode(13, firmata.OUTPUT)
proArduino.delay(2)
LEFT = 1
x = y = 0
screen = pygame.display.set_mode((640, 480))
running = 1
def blinky(pin_n):
proArduino.digital_write(pin_n, firmata.LOW)
proArduino.delay(2)
proArduino.digital_write(pin_n, firmata.HIGH)
proArduino.delay(2)
while running:
event = pygame.event.poll()
if event.type == pygame.QUIT:
running = 0
elif event.type == pygame.MOUSEBUTTONDOWN and event.button == LEFT:
blinky(13)
screen.fill((100,0,0))
pygame.display.flip()
Right now I am experimenting with a lot of diffrent things(forking etc.), to see how the arduino and pygame can best interoperate.

Sweet, I can't wait till I get my arduino board

There fun to work with for sure.

Thanks for making this bsdpunk ^__^
