Just got one of these and it uses some really clever design features - an ISP header can be added to open it up for normal programming.

I love how they used an LED as a light/dark sensor and the way they measure parasitic capacitance is just delightful! Details here.

I've been meaning to pick up some of these soil sensors, I've read a bit about them and apparently the capacitive ones are far superior to the more common resistive ones.

I like this idea and have been considering doing something on these soil sensors for a while.

Disclaimer - I have whatever is the opposite of a "green thumb", plants shriek and die whenever I'm in the room with them and I believe I'm one of the few human beings who has ever killed a plastic plant!  So the presentation would have to be theoretical, as no plant would be able to withstand being watered by me!
