Hi,
I have recently wired up an array of RGB LED lighting on my car. I have it in 8 different sections and want to make a controller that gives me full RGB Colour mixing with intensity control over each section individually. So based on this I figure I need 24 individual outputs. The LED's are all set up common anode. I have looked at some controllers available on the market, and while some do exist they can be costly, I would like to think that I could make something cheaper and also enjoy the experience of making it.
Then there is the second part. As a control device for it i was wanting to look at using my iPhone / iPad. Was hoping to work an app on it to select the area of the car then select the colour or be able to make entire car a colour. Does anyone know of any customisable apps that I could then use to talk to the control device?
I did consider using an arduino, but it lacks enough PWM pins.
Each set of LEDs is running no more than approx 3amp per colour (have not tested the exact power draw) and there is the possibility of every one having all colours on at once, so the controller would need to be able to handle the load.
Being on my car it is obviously running at 12v +- the usual allowances, max of approx 14v,
I Hope I have Given enough information here.
Cheers
Kurt
