For my final project I created a hanging plant pot that takes in data from a photo resistor and a soil moisture sensor to affect a light display.
Here are some of my initial sketches:
My actual design will be based on this sketch:
The soil moisture sensor and the light sensor (photoresistor) will be installed in the flower pot to monitor the conditions the plant is experiencing. When there is not enough water in the soil, the cloud above will flash like lightning above it at varying speeds to signal the user to water the plant. As the light sensor picks up less and less light the entire piece will have a back light that will get brighter and brighter.
This is an image of my breadboard prototype that I used to test connections and try out the code I wrote:
Here is a link to the code:
Here is a sketch of how I will build the enclosure:
This is the file I used to laser cut my enclosure out of an 1/8th inch sheet of plywood:
This is a sketch of how I will solder connections and put all the electronics into my enclosure:
