Hi folks!
I just started a little project - a thing I need to do in order to finish up a gift for my fiancee. The problem is, I am totally new to electronics. I've never build a single thing and all my electronic experience starts and ends with charging up my phone or my camera... :-D
So all these circuit plans I found on the web are really fun and nice, but I am very lost in them, although I can imagine they are as clear and simple as they can get.
I found exactly the thing I need on Youtube:
However, I started this project with exactly the same components needed for this project: http://www.instructables.com/id/LED-Cube-Night-Light/?ALLSTEPS
Since I will be building something quite similar (it will be a small box), I need all the components to be quite small and 12v battery is not exactly the smallest and lightest.
So my goal is to build fade in and fade out LED effect. Slow fade in, when the switch is pressed and slow fade out, when the switch is pressed once again. All this with 3x LEDs (LED 5mm blue; 40?; 2300 mcd; 3,3 V; 20 mA) and 2x CR2032 3V batteries (I might add up one more if it will be needed).
Now I can see there is solution and I almost came to understand it, but I simply don't have enough engineering brain cells to grasp it completely. :-D I know I need capacitor, I need some resistors etc. But which kind of capacitor to fit my batteries and LEDs? Which kind of resistors? And when I will have all that, in which order to tangle them together? The Instructables project I linked above is easily understandable for me, because it is nicely visual. I am really quite lost in the circuit plans... And I know, I could go back to my high school years and try and learn it, but I don't really have tons of time to do it, since birthday of my fiancee is drawing near.
Could please anyone help me with this and give me directions of what I should do? It would be really greatly appreciated!
Have a great day guys!
