I’m sure loads of people are building Arduino based trees this year. I was asked to build one that responds to keywords on twitter (https://www1.bournemouth.ac.uk/news/2014-12-01/tweet-tree - its not so clear from that picture but its a 6m tree!), so I set one up using a Yun.
Tech details are here. I plan to release all the code in the next few weeks, but if you’re attempting to track tweets from a Yun, I’ve attached a shell script which runs on Yun Linux, picks out keywords in tweets, counts then, and places them in the Bridge keystore, so you can write avr side code to act upon the number of tweets. It’s got a .txt extension on it, so I can upload it here, but its really a shell script!
I thought is was worth sharing, as the authentication is pretty hairy. It uses openSSL, which is available through the gun package manager.
