Follow The Light

Overview

Buying food can be very expensive. And it can be even more expensive to buy healthy food. My goal was to create an efficient way to grow plants inexpensively in the home. My idea for an indoor plant growing system was a solar tracker; a machine that could be placed beside a window and would move a plant to follow the sun and achieve optimum light levels. I used photoresistors (light sensors), an Arduino microcontroller (programmable mini computer), and small motors to follow and maximize the light a plant receives. I also incorporated artificial lights for cloudy days or if the only available window does not receive continuous direct sunlight.
