To see how to make the rose, please see my blog post over here on my craft blog, (it seemed a more appropriate place for a how to make pattern).
TLDR; I crocheted a rose, a couple of rows of which contained wire, I then sewed LEDs on the rose in a parallel circuit. This post describes how I made it flash when someone tweets with a specified string, head down to the bottom of the post if you don’t care about the code, there’s a cool video :)
What I want to happen, now I have a rose which lights up, its to have it flash any time anyone tweets with a string I specify. (The idea came from my workplace, as O2 sponsor the England rugby team, the rose is the English rose and the hash tag to look out for was one O2 was promoting – #WearTheRose).
Along with the rose, I needed an Arduino (I used an Arduino UNO), a script that looked for tweets containing the string I specified and broadcasted them to an Arduino script, which turned the LEDs on when triggered.
