Garduino: Gardening + Arduino

I just published my Instructable on getting my Arduino to take care of my plants. Specifically, Garduino waters the plants when their soil resistance level drops too low and turns on supplemental lighting to make total light daily equal 16 hours regardless of outside conditions. It’s not pretty, but it works!

Other than de-uglification, let me know what other improvements I should make and if you make your own, better version!
