Things used in this project
Final build in progress
I need a way to visualize the amount of time left for a given duration. The desire is to display how much time has lapsed for 1 hour.
IOT to the rescue! Use LEDs to display time in the shape of an octagon. Using some WiFi boards and some plexiglass, we created a wall-mounted countdown clock.
As people say, there are more ways than one to skin a cat, so I ended up choosing the Particle for the project based on the ability to control it via REST API. I also chose to use the Command Line to setup the Particle.
- Install Local Software (Photon, PhoneGap)
- Setup Hardware (Particle & NeoPixels)
- Write Device Code (logic for accepting commands and running local code)
- Write App Code (interface with the board)
Install: Particle CLI
$ npm install -g particle-cli
$ particle login
Once installed and logged in, you can then run Particle commands. To get a list of available commands, run Help.
$ particle help
Configure the board: connect the board to your computer with a USB. Then run the Setup command:
$ particle setup
This will walk you through a series of steps during Setup. You should see this at the end:
brew install dfu-util
Hello World! Let's make sure everything is working thus far with a
example. Then make an LED blink.
