Today we worked for a long time on integrating everything. I've been spending lots of time in the machine shop trying to line up holes for the housing and it's finally together! We have some adjustments to make tomorrow to make it look better. Today we tested it with our water tank and our tank sensor and surprisingly everything integrated nicely.<br />

First, the box! We had it laser cut last week and then we got to assemble this week. First, we had fun experimenting with wood glue and we ended up clamping our box by wrapping the whole thing in orange string. Next, we tried our hand at polyurethane even though we were terrified to ruin our box. It all worked out though and now we have a beautiful box! Next, we put LED's and buttons in our box. We have 3 turquoise, 3 purple, 2 green, a yellow, and red. We also have a hinged door that holds the tubing to refill the box (that has yet to be installed yet though). Here is our box in various stages of completeness! <br />

Our pump officially works! We have moved water from one cup to another! We got more flexible tubing to make the pumping easier for the motor and we figured out how to power the motor correctly. Our biggest challenge right now is making a housing for the pump that locks the motor in place.

Unfortunately, we have to make a few adjustments to the pump before it will work, but it's on its way! Our pump was able to spin the bearings without the tubing, but with the tubing in place it was not strong enough. This may be for several reasons. One thing we're going to look at is whether we're giving the motor enough current. Second, we're going to get some different tubing that is a little less stiff so that there is less resistant against the motor. Hopefully by the end of this weekend we should have some of these motors addressed.<br />

Today we tested the moisture sensor in soil with varying degrees of water added. The test confirmed that the system is functional. The values that we obtain from the arduino (via serial) are as follows:<br />
<br />
In air, not touching: ~0<br />
In air, touching: ~1023 <br />
In soil,<br />
--very wet: ~900 <br />
--optimal: 700-800<br />
--needs water: ~650<br />
--definitely needs water: <625 <br />

The button switches through the three LEDs (modes). After five seconds, the LED fades away to a dim setting so that we can conserve power in the long run.<br />

The last step will be to clean up the code (for modularity).<br />

What do we mean by parenting style? As previously posted, we want the user to be able to choose how often they are notified by the system. He or she will be able to choose one of the following modes:<br />
* Hands-off<br />
* Active<br />
* Helicopter<br />

The first CAD modeling was done to be discussed in class today (snapshots below). For now, the product has the following components:<br />
<ul>
<li>Top Plastic cover, on which the plant pot will sit (LOGO visible on top)</li>
<li>Notification system, with diffused LED light that becomes brighter as more user attention is needed. This notification system uses the LCD display screen in order to communicate where the attention is needed. For the scope of our project, the only notification is to refill the water storage unit. We are designing it so that future expansion is easy: we could add sensors to detect the amount of light hitting the plant, the humidity of the room, etc. and have the notification system alert the user for all the situations. </li>
<li>On/Off power button (left side)</li>
<li>LCD screen (front side)--to display where attention is needed</li>
<li>Level of involvement options (right side)--three options each with a push button selection </li>

<li>Hands-off</li>
<li>Present</li>

Here's a compilation of the information that we want to keep in mind as we continue to design our system: <br />
<br />
<b>General Information on Watering:</b> <br />
<ul>
<li>Under-watering and over-watering can be detrimental to a houseplant; improper watering is the cause of most household plant problems.</li>
<li>Best way to determine whether a plant needs to be watered is to check the soil moisture. </li>
<li>Most potted plants must be allowed to reach an appropriate level of dryness between waterings.</li>
<li>Amount of water needed per watering depends on the species of houseplant. </li>
<li>Water should be poured slowly over the surface of the soil until is begins to drain out of the bottom of the pot. </li>
</ul>
<b>Hydration Measurement Guidelines:</b><br />
<ul>
<li>Soil should be dry 1/4 inches down</li>
<li>Tapped pot should sound hollow</li>
<li>Weight can be a good indicator for small household plants</li>
</ul>
<b>Watering Techniques:</b><br />
<ul>
<li>Water from the top until moisture drips out of the bottom of the pot.</li>
<ul>
<li>Discard draining water</li>
<li>Don't let bottom portion of the pot stand in water</li>
</ul>
<li>Water from the bottom by placing the plant in saucer until the top of the soil is moist.</li>
<ul>
<li>Remove plant and let excess moisture drain out of the bottom.</li>
<li>Never keep the plant in standing water continuously.</li>
</ul>
<li>NOTE: Water all plants from top once a month to prevent mineral or salts build-up (white/brown crusty material on soil/rim of pot). </li>
<li>NOTE: Frequent watering with small amounts of water can lead to waterlogging </li>
</ul>
<b>Warning Signs:</b><br />

<span style="font-size: 13px; text-align: center;">We may need to research and find a different one. Perhaps one that doesn't require 120v to power it.
