Botanicalls, the project that lets your plants let you know when they need water (Radar post), has expanded beyond their Asterisk-based voice system. Now you can learn how your plants are doing with a DIY kit that lets them Twitter you. The system uses Arduino, the open-source board featured in Making Things Talk. The instructions they’ve included are very detailed; this looks like a great starter project if you’ve been thinking about experimenting with Arduino.
You’ll be able to see the project in person at ETech during our Wednesday evening ArtsFest.
