Bend sensor + heliotropic plant + Arduino

MAKE Flickr photo pool member Mleak writes –

“This was a project I did for my electronics art class. A bend sensor along one of the stems of a highly heliotropic plant is attached to a servo motor. When the plant passes a certain threshold as it leans toward the light, the servo turns it 180°, requiring it to begin its stretch over again, always leaning, always straightening.

Here’s my arduino and breadboard. The two lines leading out the bottom are the bend sensor. I can put up the arduino code if anyone is interested, but it’s pretty simple. “ – Link.
