Hi all,
I'm a circuits novice (I've taken one circuits class). I'm working on a project where I need an LED light to start off and then gradually increase in brightness when I push a button. I am trying to do this by putting a capacitor in parallel with the LED, but it is not fading in. Maybe it's fading in too quickly but it looks like it just comes on immediately.
I just need it to be very simple i.e. I press button, light fades on. Ideally I would like to be able to have it fade in in about 5 seconds or so. Is there a good way I could do this?
Thanks a lot.
