And with the Arduino platform, you can apply programming to real-world problems through accessible DIY kits. This one can be rigged to automatically water up to four plants for you.

However, since different plants require different amounts of water, you're free to modify the Arduino code's thresholds to suit your specific plant.

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting real-time data on soil moisture, temperature, and sunlight. From sensor ...
