RGB LED night light

josh_j
josh_j over 12 years ago

Ok this is what I'm trying to do. I want to create a RGB LED night for my girlfriend using an Arduino and have the LEDs fade through different colors. I want to drive at least 6 LEDs. I've been talking to people on the Arduino Google+ group but this one guy gave me a schematic for my idea, but I'm really really new to all this. Is there a driver board for RGB LEDs that I can buy and use that and the Arduino to make this? I just want something that will do what I'm planning but is easy for newbies like myself. It would be cool too if the Arduino could detect the ambient light in the room and come on as needed. I would also buy a 9V wall adaper for so the Arduino could run off power from a outlit.

 

If someone on here is able to help me work through this project and give me ideas and easy ways of creating this for my GF that would be amazing!

 

P.S. I have a Arduino Uno

 

Thanks!

Josh

    By chance did you look at the Adafruit tutorial.? I'm sure the fact you did the code (rather than have someone else supply) will impress you girlfriend. mark

    Cool project! You'd have to add the variable resistor to one of the analog inputs, and then use analogWrite to output to the LED. Oomlout has a basic example (See "Making it better, Control the Brightness…

    You say that you have an Arduino Uno?  It is great for learning digital interfacing, experimenting, and making your own projects, but the Picaxe can do all the same stuff and is 1/5 the price.  Even the TI LaunchPad w/Energia (Arduino like IDE) is very low cost compared to UNO.

    That's great information, however not helpful. Does anyone else have some actual help they can give me?

    If it is not too much trouble, you could post the schematic and your Arduino Sketch and I am sure there will be some feedback provided by the membership.

    All I want to know is there simple premade RGB led driver board I can buy and wire it to an arduino to make a simple night light.

    Well if you provide the specs of the RGB LED you are useing you may not need a driver. A simple transistor of FET might be enough.

     

    But here are a couple from Sparkfun,
