    Default Basic Arduino Controller for LED Systems

    For those of you asking about a simple controller I have made up a shopping list for a basic controller with enclosure and 16x2 LCD that will control the following and leave open 6 extra pins....
    2 Temp Sensors (Water and Heatsink)
    2 powerheads
    1 fan (temp sensor controlled)
    1 heater (temp sensor controlled)
    1 moonlight (on/off)
    1 fuge (on/off)
    1 White LEDs
    1 Blue LEDs

    If your using meanwell drivers you would also need to buy a pkg of 2N2222 Transistors and a 10v DC wallwart to be able to use the 0-5v signal for a 0-10v driver.

    Shopping List for basic lighting control

    Uno
    RTC
    Enclosure
    Power Supply
    Waterproof Temp Sensor
    Heatsink Temp Sensor
    LCD 16x2 - White on Blue Bkgnd
    I2C LCD Controller You will need to download the new Liquidcrystal library from them for this to work.
    8 Relay Board 2 powerheads,1 fuge,1 sump, 1 Heater, 1 Fan, 1 moonlight
    2-4 - 110 Outlets
    1 - 8x7 Radioshack Project Box to hold relays and outlets.
    Lots of wires....lol

    This unit will give you a 0-5v PWM for CAT4101 Drivers or buckpucks.....if your going with meanwells or any other LED driver that requires a 0-10vPWM signal follow the guidelines in the attached pic.Make sure the 12v power supply is under 600mA.

    SaltyDog,, I almost have my build done, but running into a few issues with he code i was using.

    my screen scroll works, temps works, clock works, relay 1 and 2 shut on and off, 3 and 4 don't do anything?
    I will test the led ramp up and down i hope today, I have three 48p drivers, no pots. 24 rb cree , 12 white cree.

    The moon and sump light I was wanting on the same outlet, and fans to be temp controlled on another out let.
    4 relays, 4 outlets

    the code i have has the \ph, and orp
    But I do not plan on building the sensors any time soon.

    ebay parts, all from same seller
    I have the ebay uno with 16x2 and buttons
    4 relay 5v
    rtc
    2 temp sensors

    all the other odd and end parts i went to radio shack.

    but like i said, So far I am at a loss on why the last 2 relays do not come on, if i swap channels they will.
    Thats why I think its the code.

    If you can help, just let me know and i will post what pins i have what on, and the code i have.
    I will play with the code you have posted, just to see if i have any luck

    Yeah. Let me look at the code. I'll have to decipher the Arduino code. It'll take me a bit.
