A Cyberplant that is light
sensitive. Light patterns change if you walk past and cast a
shadow on the plant.
Uses Jessa Flower modules built by Stan Cohen at Bira
with all the charm and calming effects generated with white light
emitting diodes. Flash and flicker modes can be set at turn on. Makes a
great centerpiece on the dining table with the lights turned down.
Shown at Robogames 2006
I used the Jessa Flower modules to
make an artbot work called "Sensitive Plant". A Picaxe
Microcontroller senses changes of light intensity and causes a brief
interuption of the power to the modules. The interuption causes
the module to switch to a different light pattern. You can see the
controller just below the top of the vase. The light dependent resistor
protrudes at the opening of the vase.
Controller with light dependent resistor at one end.
