pebble / toilet-time

Arduino/Web/Pebble Application for determining the optimal time to use the toilet

Toilet-Time

Get the status of a bathroom lock on your wrist so you know when it is toilet time.

This was developed and iterated to solve bathroom queue issues at Pebble HQ and was later evolved into a public example application for presentation at JSConf 2015.

This project is made up of three components: An Arduino firmware, a watchapp, and a NodeJs server.

The Arduino that pushes the status of a lock-attached switch to a NodeJS Pebble Timeline server. This server in turn pushes Timeline Pins to the "toilet-time" Topic. Watches with the watchapp installed subscribe to the "toilet-time" topic and get updates on the lock status.

Requirements

• Arduino-compatible dev board.
• Arduino-compatible Ethernet Shield
• Switch of some kind
• NodeJS capable web server
• Pebble Time / Pebble Time Steel watches
• Pebble SDK installed
• Pebble Timeline API Key

Setup

1. Install server dependencies

   cd timeline-server
   npm install
   

2. Start Server

   API_KEY="YOUR_API_KEY" npm start
   

3. Adjust Arduino code to point at your server:

   cd lock-status
   sed 's/__HOST__/YOUR-DOMAIN.com/g' -i lock-status.ino
   

4. Upload firmware to Arduino

   arduino --upload lock-status.ino
   

5. Connect switch to +5v and Analog Input 2 on Arduino

6. Attach switch as such that it makes a circuit when door is locked

7. Build Watchapp

   cd watch-client
   pebble build
   

8. Install Watchapp

   pebble install
   

9. Enjoy watching your Timeline update when the lock status changes :D
