Resulting Prototype

For two-way communication, we designed a workflow synchronizing the two lamps. Whenever either lamp rotates 90 degree, a microcontroller (Particle Argon) reads the rotary encoder position changes 5, it would not only control its wired neopixel to change to the next or previous lighting mode, but also publish an event to the cloud platform, and the other microcontroller that has subscribed to the event would control their wired neopixel to change to the same. See the following workflow diagram and script for more.
