I've got an arduino, and done almost all of the arduino tutorials and the adafruit ones. The project I'm looking to do is using the Warm white LED waterproof flexi-strip for undercounter lighting, using the 12V 5 A switching power supplies for power, and an attiny of some sort for PWM dimming. I'm going to have to do it in 2 sections, to stay under the 5A that each supply provides, and avoid fishing wire through the walls.
My questions are, on the differences between different attiny models, there are 25 stocked atmel microcontrollers on mouser under $2.00. I've not yet seen a chart comparing them. Little charts comparing 3-4 in a series, but nothing else. I'm seeing various PWM examples using just about any attiny. Are there any differences that will affect this application? I'm only going to need 1 pwm output, and possibly one analog in. Any differences in how they are programmed?
Finally found a post where someone did almost the same project, http://www.instructables.com/id/How-to- ... de-effect/
so now planning to start with their plan, but use an attiny, since I don't have a mega laying around.
I'm going to have to figure out what changes in wiring and programming have to be made
They did manage to set up 2 levels of brightness with no controls, going to have to look closely at that, and figure out if I want a live adjustment of dimming level. Probably have to get the parts and test in place and see how it looks.
Is there anything else that I'm overlooking? more or different capacitors needed than they used? I'm going to have to order most parts besides resistors anyway, so trying to find out what I need ahead of time. I'm figuring on testing on a breadboard and moving to permaproto, haven't figured out enclosure or mounting location yet, probably keep it thin and hide it under the counter.
