Since a couple of weeks Ghent has it’s first hackerspace named Whitespace (after the street it’s located : Blekerijstraat).
Whitespace is driven partly by a bunch of people who started/helped growing, hackerspace Brussels but live in Ghent and wanted to skip the commute. The other part are new enthousiastic locals (like me) who are commited to build something great.
In this tutorial I’ll show how to install IDLE for Python 2.6 on Ubuntu 9.10
This tutorial couldn’t be much easier, as a matter of fact you should be ashamed of yourself for even reading this! I’m just kidding, follow the next couple of steps and you’ll be wrestling the mighty python in a matter of minutes.
An arduino, a DB18S20 one-wire temperature sensor and an LDR (Light Dependent Resistor) are hooked up with some resistors and an ethernet shield to make a datalogger and webmonitor.
Since today was a holiday (here in Belgium) I had a few moments to spare so I wrote a quick and dirty version of pong for the arduino using the S65 shield.
MAKE made another excellent video with Collin Cunningham. This time it’s on how inductors work. Learn more about wire coils and their capacity to store energy in electromagnetic fields.
In this third and final part I’ll show you how to get the arduino to access a website using an ethernet shield and php. The data can then be displayed in a number of ways. Here the data is simply printed one line at a time.
Each time motion is detected, the networked arduino connects to the web and executes a php script which writes the time and date of the event to a text file. When you want to check if motion was detected, acces a different php script which displays all (if any) recorded events.
Check my next post to see how to send sensor data from the arduino to a website using php.
If you followed part 1 and part 2 all you need to do for part 3 is change the code of the receiving arduino since we’re only changing the output from ‘blink a led’ to ‘access a website’.
