Chasing circle of LEDS...? Answered
I'm in the process of making a UFO model for the local Railroad museum's model trainset. What I want to do is have the standard disc shaped UFO with embedded LEDs on the edge. I would like the LEDs to chase around the edge repeatedly while the display is on.
I've looked into using Arduino, but size is a factor. The UFO is going to be about 6" across. As far as I can tell, I can use a 555 and 4017 to work it out, as but that limits me to 10 leds, right?
If it can be worked out, having counter rotating circles would be great... But that would be duplicating the circuit and reversing the 4017 pin outs...
AND...where is a good place to buy small quantities of LEDs and ICs? My local Radio Shack has nothing in stock
