I bought myself a LED strip which works with 12v. I cut a small piece of it off, so the current wouldn't be too high for my breadboard. It works now.
I'd like to be able to do "dumming" effects on it or maybe some kind of fade-in when I turn it on but I'm not sure what is a good way to go about doing that.
- At first I thought I'd use analog output and somehow scale the 0-5V output to 0-12V.
- My other thought is that I could use a PWD signal with ever-changing duty cycles and high enough frequency that I don't see the "flickering".
What do you people think, are both of these approaches viable?
How would you go about making a circuit for No. 1 (basically I'm asking to google search keywords )
