Turbine monitor minecraft tekkit

-- TurbineMonitor
--  Made By: MrKMG <mrkmg.com>
--
-- This program will keep your turbines up to speed
-- and turn the coil on and off as needed.
--
-- To Use:
--
-- Attach as many Turbines and Monitors as you
-- would like via wired modems. Monitors will all
-- display the same information for each turbine:
--    Current Speed
--    Current Power Generation,
--    Coil On/Off
--    Flow On/Off
--
-- Monitors can be of any size
--

--Edit these to fit your turbines

-- Speed to keep rotors between. Recommend putting
-- just above the best your turbine can do.
minSpeed = 1800
maxSpeed = 1820

-- Range of RF to keep in turbine. Recommend to
-- keep low to avoid waste.
minEnergy = 1
maxEnergy = 200000

-- Colors for the monitor

uiColors["flowOffBackground"] = colors.red
uiColors["flowOffText"] = colors.white

-- Text for the monitor.
