Much has happened since the last blog update! We now have two days left to work on our product untill there's show off time for Kaj and Tim friday. Søren G and Alex has been assigned to work on the arduino-part of our project - getting the LEDs to light according to specific pressure on pressure sensors. They have also worked on the physical design of our product. So far, the display has been made and the seat is still to be formed. Trial and error for finding the right LED's as well as finding the right resistance has been made.
The use of wireless communication from the arduino board to our database has been downprioritzed in favour of finishing the physical design and getting the product ready for show off friday.

Søren D. and I have been working on the web-tech part of the project. We have designed a homepage with statistics for the staff so an overview of the sitting habbit of a given resident can be presented. The big challenge has been to set up our own database using MySQL, as this is something we have not done before. Getting the database to communicate with our web-services as well as incorporating that into the Google Charts has been a great challenge. The graphical design of our webpage, the CSS, has taken a lot of time to write but has not been esspecially technically challenging.

Automatically update of the MySQL database with the data (pressure intensities) parsed from arduino is the number objective to get to work at the moment. We hope this will be achieved today, so thursday can be used to polish the features of our product which currently work.

Below 2 pictures of the LED's and display design is presented.
