Killing plants is easy, but keeping them alive and healthy is a lot more rewarding. If you have a black thumb and need a little help keeping your indoor plants alive, this project from Make shows you how to build an Arduino-powered monitoring system.
The system connects your Arduino to a number of sensors and displays those readings on a small LCD screen. The Arduino can monitor light, heat, and moisture. With all that data in tow, you can keep your plant alive and healthy pretty easily. Head over to Make for the full guide.
