Soil Moisture Sensor with a Cool Neopixel Display
Built this soil moisture sensor for my wife as a high-tech replacement for one of those resistance-sensing soil moisture sensors that you can buy at hardware stores. Uses an microcontroller connected to a Neopixel panel that I have programmed (using CircuitPython) to track moisture content. You can see it in action in the movie below. I will post the design to Adafruit Playground at some point.
