Thank you for this post! I think that this may be exactly what I am looking for.. Light up all LED's one by one and leave them on, once all are on... reset, right?
I have never dealt with decade counters before, I have a PICkit2 programmer, But have failed to figure out any information on programming a CD4017B, so I am not sure what I am supposed to do with the asc file.
I would like to try and have this circuit completed by December, for my wife's graduation. I would like to verify the parts list with someone, if anyone would be so kind.
100 leds
20 2N3904 transistors
2 CD4017B decade counters
10 1k ohm resistors
1 300 ohm resistor
1 220k ohm resistor
1 200k ohm resistor
2 100n capacitor
3 CD4093B NAND GATE "Schmitt trigger quad NAND package"?
I would truely appreciate any help at all.
Happy wife, happy life right?
