Howdy!

First of all, I understand electronics on a kindergarten
level. ...but I'm a keen study!

I have a project idea in my head that I would really like to bring to
life. I want to put 16 LED lights in a circle and have them "chase"
each other. Random patterns would also be great (ie: two lights
moving clockwise and anti-clockwise from the 12 or 6 o'clock position
and then back), and if it's possible, a couple of "faded" lights
behind the leader.

Can you even fade a diode? I'm not even sure.

Either way, if there is a kit available or if someone has a URL they'd
be willing to share, I would really appreciate it.

I have a handful of 555 timers as well as a breadboard. I will be
sourcing LEDs online shortly.

Many thanks!
