Okay, I need to do this....
Cycle six LEDs on, about 1 per second in the bar-graph style...that is, the preceeding LED remains lit when the next one illuminates. When all six LEDs have lit up in turn, I need them to all simultaneously extinguish, and start the process over again.
I've seen loads of 'knight rider' type sequencers and bar graph circuits, but none that does this sort of "Old school neon sign" kind of sequencing.
I have no desire to use a pic or stamp. I know my request is easy to achieve via programming, but I have no desire to setup for that. I'd prefer to do it with standard ICs, like the 555, 4017, LM391x series and logic circuits.
Many thanks in advance for your thoughts!
