so im building a simple light chaser circuit out of a 4017 counter and
555 timer. the 555 timer circuit works. my problem is with thr 4017.


according to several schematics ive seen...and behavior in electronics
workbench/multisim, connecting the reset to output q4 causes the chip
to reset when q4 fires.


real-life behavior i different. if reset is connected to anything
except just ground, all it'll do is blink the first led.


any suggestions?


You're resetting from the wrong end of the counter.


i dont see how. the counter will start with output q0....it
automatically cycles back to q0 after firing q9, the reset is supposed
to allow me to recycle back to q0 after firing a specific number of
leds.

explain your reasoning or stfu.
