Chatting Plant
Version 1 - Last update: Oct 4, 2015

Circuit connects a moisture sensor (two nails) to analog pins to digital pins (out) for a Twitter feed.

This circuit is designed to have an Arduino board connect to two nails placed in soil to measure moisture level (0 to 1023). The nails would be connected to 5V, GND, analog in and digital out pins on the Arduino. The Arduino would then use a loaded sketch dividing the moisture level into 20% increments (i.e. - 81-100%, 61-80%, 41-60%, 21-40% and 0-20%).
