Overview

• Create your own cool 3D animations and tag them
• Upload to your Cube4Fun
• Use the animation-tag from any internet service/device by sending GET/ request to activate animations
• Share your animations with everybody on this site:

Requirements

Software

Cube

The communication is working through I2C protocoll. The basic logic is very simple:

• Display programmed smooth animations
• If a frame (full 64 led values) received, display it
• 5 seconds timeout for the default state. (Currently displaying programmed animations)

Protocoll

• Only listen, no call backs
• valid format for a frame:

Key	Position:"Value"
Start key	0:"/" 1:"/" 2:"?" 3:"?"
Payload	4-68:"0...255"
End key	69:"," 70:"," 71:" " 72:" "

Hardware

Because most of the esp8266 boards are working with 3.3V and our Cube board is a regular ATMEGA328 with 5V, we need a voltage shifter. This is a basic schematic realized with a BSS138 MOSFET. Breakout boards are available on most popular sites.
