Beginner's guide to building IoT devices

The gist

Ever heard of an Arduino? It's a $35 microcontroller that lets you write code that interacts with motors and lights and IRL stuff. Well, there's a $2 version that has all the same features and is the size of a postage stamp. It's call the ESP8266.

The ESP8266

ESP8266 is an inexpensive wifi-enabled SoC made by the company Espressif. It was released in 2014 with very little documentation but its low cost motivated hardware hackers around the world to explore and document the module. Online communities formed to discuss the chip and how to build with it.

Core

CF-Core acts as the backbone for Capital Framework. It's made up of four child components cf-vars, cf-media-queries, cf-utilities, and cf-base.

Vars

Theme variables for setting the color and sizes throughout the project. Overwrite them in your own project by duplicating the variable @key: value.

Ex. to set your base font size, add @base-font-size-px: 17px; to your project.
