An OpenComputers lua module for controlling Mi-Light brand bulbs (and LimitlessLED, etc)

#Info

---

It includes modules for sending commands to the Mi-Light bulb and for using the robots from the Minecraft OpenComputers mod to detect color from adjacent blocks and relay to the bulb.

OpenComputers Documentation

#Installation Your OpenComputers Robot/Drone/Computer needs an internet card with its module installed.

wget https://raw.githubusercontent.com/alexwh/milight-opencomputers/master/lib/bulb.lua /lib/bulb.lua wget https://raw.githubusercontent.com/alexwh/milight-opencomputers/master/lib/block.lua /lib/block.lua

Or, just copy the appropriate module files in the lib folder to your systems /lib folder.

#Basic Usage Here is a basic example of how the module works:

-- OpenComputers module for selecting which face of a block to calculate
-- commands from e.g robot.detect()
side = require("sides")

-- module for interfacing with Mi-Light bulb
bulb = require("bulb")

-- module for detecting block characteristics with the geolyzer
block = require("block")

bulb.address = "192.168.x.x" -- Set the address of the Mi-Light bridge

-- changes the color of the bulb to color name based on a colormap table
bulb.color("green")

-- use a specific numerical value between 0-255
bulb.colorNumber(100)

-- get the block name
block.get() -- -> e.g. "minecraft:air"

-- gets the color of the block on the defined side (defaults to side.forward).
-- also converts the decimal given by minecraft to it's corresponding number on
-- the Mi-Light scale of 0-255
block.getColor() -- -> e.g. 120

-- combine the two to set the light color to the detected block color
bulb.colorNumber(block.getColor())

Notes

• After syncing the bulb to the controller with the phone app, you must change the transmission mode to TCP-Server in the controller webui settings (browse to the IP, credentials are admin/admin). Be aware that the phone app only works with UDP, and OpenComputers only works with TCP.
• Some Mi-Light bridges seem to have different command prefixes. The most common seems to be with 0x4. Because of this, 0x4 is the default. Originally, the bulb that was tested with this used 0x2 instead. A copy of 0x2 commands have been included, commented out.
