I love the Garduino! I really think it is one of the coolest projects that you can make with the Arduino. The full Garduino has some really great features it waters the plants only when needed, turns on supplemental lights based on how much natural sunlight is received, and alerts if the temperature drops below a plant-healthy level. Eventually I’d like to put one of these full garduino systems together and perhaps even add to it. For now though I just have a simple low maintanance desk plant that I just need to remember to water. I took the Garduino concept and simplified it. My super simplified garduino uses the same circuit as the full garduino to measure soil moisture level. When that moisture level drops too low an LED positioned above the plant lights up letting me know it is time to water. Below is a video I made demonstrating this project in action.
Future additions to this project will include:
1. Replacing the LED with an edge lit “water me” sign.
2. Create LED water level indicator.
3. Make it smaller.
