An RGB led that indicates whenever you get a new follower, comment or like on your Instagram account.
The server listens for http connections on port 3000 (locally).
Two routes are configured:
/followers/[instagram_handle]/likes/[instagram_handle]/comments/[instagram_handle]
The server will cache the result of the Instagram queries and return the result as plain text (no json-wrapping BS) to the calling client.
The photon will call the Node.js server every x second, asking for the current number of followers/comments/likes.
A simple in-memory cache of the latest result allows us to calculate the delta for the two values. Therefore we can know when something has changed.
This guide assumes you are up and running with nodejs and npm
1) Install dependencies
npm install
2) Run the project:
node index.js
This will start the node project on your local machine and will listen for http connections on port 3000
Note: I recommend hosting the node application somewhere like Heroku
Visit https://build.particle.io and upload the code to your Photon
Modify the code
- Configure your own hostname of the nodejs-application
- Replace my Instagram handle "engineerish" with your own
- Do any necessary modifications to the pin config (or write your own "result visualization" code)
