Our current experiments will test the energy needed to produce the sound for various numbers of plants. Knowing that plants can control sound, we hope to apply the same concept to lights as well. To translate the electrical signals between plant and machine, we are using an arduino board. We are also hoping to design a new system of solar collection, using photoreceptors in a cartesian format. These sensors, in combination with connected motors, will direct a shield of panels in the direction of the strongest light to collect the maximum amount of energy. We are using the lego mindstorm program to design and build this system.
