Hi, i have made a simple astable 555 timer circuit connected to the clock input of a 4017 decade counter.
I am getting a pulse from the 555 timer (i have an LED connected direct to pin 3) but output 0 stays on on the counter (where i have 6 LED's)
the 4017 has power (+/-), a reset (pin 5 to pin 15 so it resets when it gets to output 6)
The problem is, only the 1st LED lights (output 0) it does not flash either, just stays on
Any ideas?
Mike
