Thank you in advance for any help that you can provide.
You have helped me twice before on my Daughters school projects (I did not post but the information was here and helped me.) So far we did a simple solar panel and led to illustrate renewable energy on a poster and then later we used a 555, decade counters (4017 + 4022) and potentiometer to create the earth's orbit on another poster using LED's in variable sequence. VERY cool. It has made both of my Daughters interested in electronics and we already made a couple of those Velleman kits.
I have searched but I can't seem to come to a clear answer on how I should tackle our next project. We built an ocean reef diorama in a large shoe box. We would like to use six soft white or blue [or both] LED's staggered on top of the box to create the illusion of how sunlight 'dances' through shallow water.
I believe that six LED should do the trick and that two LEDs should be on at all times then either fade out or just swap out to the next pair with a total of three pairs. Did that make sense? 6 LEDs. 2 on at a time. 3 pairs.
I would greatly appreciate any input. I would like to keep it small [if possible] and I don't care about # of components. I do not even have to put this on strip board as I can spread the components on the back of the shoebox (I will if I need to of course). My main concern is HOW do I pull this off?
Notes: LEDs are coming from 75% off Christmas lights (3mm or 5mm) – various colors, no specs. I have a lot of 3 volt CR2032 ‘button’ batteries and holders. I do not need to run the LEDs at full power (I know I can adjust that via resistors value once I have a setup). Must be done by this Friday so simple is likely better in this case. I will breadboard it to test. That should cover it.
Again Thank You in advance for any and all suggestions that you all may come up with. It is very much appreciated.
