Scenario & Purpose

To keep track of how much water I consumed during the day, I designed the prototype that employs a force sensor and a light sensor. It will track only when I drink a certain amount of water during the daytime, which means the force reading and light reading need to be high enough to trigger the tracking system.

Code & Sensors

The amount of water is measured by the frsReading; day or night is judged by photoCellReading. The variable drink indicates whether I just put a glass of water on the force sensor during the day.

To connect Spark with my Twitter account, I'm using IFTTT to monitor the drink variable and let it tweet when drink turns from 0 to 1.
