Hello, I plan to create a mist machine that can be tweeted to activate it.
The unit will not have mains water supply, I will use a unit with a storage tank - http://www.cloudtops.com/misting_systems_misting_nozzles/misting_systems.php
I will not be able to fit an ethernet cable, I plan to use the wiFly shield with an arduino Uno. Tweeting the unit will activate the pump. http://www.sparkfun.com/products/9954
A couple questions..
Will the wiFly shield work with the twitter library? What is the best way to get an instant result from the fogger? Will a transistor work when trying to control the power to the fogger from the arduino?
