Hi guys,
Just want to ask a question and see if people have experience in this area, or if this idea is even possible.
I want to make a machine that is fuelled by tweets or instagram shares and the machine will aid the growth of fungi.
Is it possible to turn a lamp on with a tweet? Or to release a spore of fungi into a petri dish? I am inspired by the twitter activated vending machines used as marketing for many companies in 2014.
I am open to use any hardware especially Arduinos and Rasperry Pi’s…
Looking forward to hearing back from you guys on this!
Grace

Hi,
I can confirm that you can activate anything you want with a tweet, but since february (more or less), Twitter imposed new restrictions, and you can’t make request as frequently as before, ( I don’t remember exactly what is the shorter delay authorized , about 1min I think ) so the response to your Tweet may suffer of a delay …
There is a java library that works well with the Twitter API : [Twitter4j](http://twitter4j.org/en/index.html).
You can compute your twitter data with Processing and then send directives to an Arduino board through a USB port. And Arduino will be in charge of the electronics.
Or use Processing for Raspberry, as you want.
PS : Be aware, to be able to use the Twitter API, you will have to ask a dev account, wich can take few days.
