This project shows a simple example of how to use a float switch and pumping station to refill a reservoir once the level gets too low. For our example we use a small aquarium, but this same project could be used for pet dishes, water fountains, or any other number of similar applications.
Project Parts List:
|Device||Sensor Shield Port|
|Float Switch||Digital Pin 2 One wire to signal / one wire to ground|
|Pumping Station||Digital Pin 4|
|RobotGeek LED Board||Digital Pin 7|
