Project connects Twitter to a plant watering system - send a tweet mentioning the account name, and a few drops of water will be given to the plant. There is a webcam to see the process happen:
@JarroseLaPlante is an installation created by Félicien Goguey and Thomas Meghe. A plant has a twitter account, when you send her a tweet you water her with a few drops. Because a single tweet can’t save her, she needs the twitter users’ collaboration to grow up !
A Processing application listens to new tweets via the Twitter API. The servo motor which bring water to the plant is piloted through Arduino. Moreover a sensor enables to check the humidity rate in the pot, if it’s too high the installation is blocked, if it’s too low the plant tweets in order to alert her followers.
If you follow the plant, she can send you private messages. Only public tweets can activate the installation.
