Final Project -- A Steam Boat Water Quality Monitor
Design Idea
A small RC boat that can move around a pond, measure the water quality, and produce steam that changes colors according to the water pollution level. Several effects can be achieved: "smoke" (white LED), "poisonous gas" (green LED), and "on fire" (orange LED). When sitting still on water, the boat can simply function as a household humidifier.
The remote controller for the boat can be implemented by the magic wand idea I had in the input devices week with some added buttons.
