Garduino: Geek Gardening with Arduino

I wanted to start gardening, but I knew I wouldnt keep up the regular schedule of watering the plants and making sure they got enough light. So I recruited a microprocessor and a suite of sensors to help with these tasks. An Arduino microcontroller runs my indoor garden, watering the plants only when theyre thirsty, turning on supplemental lights based on how much natural sunlight is received, and alerting me if the temperature drops below a plant-healthy level. For sensors, the Garduino uses an inexpensive photocell (light), thermistor (temperature), and a pair of galvanized nails (moisture).”
