    Dear all, I would like to create a simple circuit that can slowly (takes about 1 second to) glow up a LED. I have tried to connect a capacitors, resistors and LED in series but it doesn't work.. Any suggestions?

    Introduction and PaintCAD , Chapter 12

    There are many ways to do this. You need to define your application better. I suspect a simple transistor added to the rest of the mix will get you where you want to go.

    The first post I showed is a comedy in misunderstandings, but we eventually got him where he wanted to go.

    In the second link (which is an article and tutorial I wrote) look for "comet trails" in Chapter 12.
