I uploaded the files but forgot to post them in the blog!
The code for the Wiring board can be found here: http://xdesign.nyu.edu/feralrobots/idogblog/bean_wiring/
And the Processing code and song can be found here: http://xdesign.nyu.edu/feralrobots/idogblog/bean_processing/
Yay for a great project! :o)
we tested our sensor (TGS 822) again today and the circuit is working well. we used a dry erase marker as our ethanol source and the voltage reading gradually increases as the pen got closer to the sensor. now, time to work on the wiring board!
They haven't responded to ANY of my emails, not even the cancellation emails, so I'm worried that one day, when they get off of their lazy asses, they'll charge the order and ship it. I'm going to give them a call tomorrow, hopefully someone will answer...! Will post again as things happen...
