Hexagon LED

Objective:

Build a small, inexpensive hexagonal lighting PCB with an inexpensive microcontroller that can communicate using slow-speed software serial with the other attached nodes and to an optionally fitted ESP8266 ESP-01 module which will designate itself the “host”, and populate out colour information from the center.

A serial mesh of communication between each interlinked hexagonal node.

A REST service running on the ESP sat on the users Wifi allowing for colour information to be pushed from an app or script.
