Story

YouTube video showcasing the completed project and all steps. The project itself is shown working, along with footage of live data being updated via Google Sheets.

A water-pump system designed to fill a bowl from a tank of water. This was designed to fill a dog bowl with about 2 cups of water with each time the device is activated. The amount of water can easily be changed to accommodate your desired fill level.

This displays the pump submerged in the large water container

This figure displays the water pumped into the bowl.

The positive and negative of the DC relay is connected to the D7 and ground of the first photon.

First photon connected to the DC Relay with the water pump plugged into normally off

The second photon is programed to publish an event which controls the first photons D7 led. Once the first photon receives the event to turn on its D7 led, it will publish an event back to the second photon turning its led off to let that person know the event was received.

Upclose of the second photon

Upclose of the first photon

The website IFTTT was used to track the amount of water dispensed over time. This website works by registering each event published by the second photon as a new row in Google Sheets. Sheets was then programmed to sum all the events as a graph of the total volume dispensed.
