I am new to Arduino and I have an led project i'd like to attempt. I have 5 x 1m strips of led's operating on a 12vdc supply. I need to have them switch on sequentially, but with fading. When triggered, strip 1 needs to fade in to maximum brightness, stay on for 2 minutes and fade out. Strip 2 will then fade in and do the same for the rest until strip 5 fades out. Sequence would then start again. I have fairly good electronic knowledge but not on arduino. Please advise as to what I require to get me started. Thanks Guys.
I'm assuming you are using static strips. Meaning, The four wires are 12V DC, Red, Blue, and Green. (not in that order, possibly). For these types of strips, what you want to do is impossible, unless you connect each strip to it's own ports in the arduino (All can use 12 V). However, if you want them to fade, each wire would have to be connected into a PWM Port. I know for the arduino, there is only 6 of these (So only 2 total strips could fade). So for 3 colors * 5 strips, you'd need 15 PWM ports.
You may be able to do it with a latch and such. But pure Arduino, it's impossible.
**Note: I'm also assuming you're using RGB LED strips.**
