Anjelica & Albert: Posh Plant Video
After initially not knowing the direction of our project, Albert and I decided to create a planter that would alert users of its water needs. When comparing our end product to our initial diagram, the concept changed very little, if at all. Essentially, the Posh Pot (named because our current version is British and snarky) detects the moisture levels in the potted plant's soil. Albert and I crafted our own moisture sensor by using spare copper wire,two nails, and some electrical tape. If the soil is acceptably damp, the planter turns on 3 blue LEDs. However, if the soil is too dry or too wet, the plant will comment on its state when someone walks by. This is detected through the motion sensor located in the front of the housing. The Arduino and wires are all housed in the base of the planter.

Here's our code for the planter. We could spend hours, days even, staring at our code wondering why something wouldn't work - - - only to find out that it was a hardware problem causing the malfunction. Such frustration, such a good learning experience :).
