Default Re: Turntable Stroboscope

I suspect the confusion on the output names simply comes from whether the output of the first stage of the counter (not brought out to a pin) is 'Q0' or 'Q1'.

Using the naming you are using, logically AND Q11, Q12 and Q13. That's pins 1,2,3 of the 74HC4060. The wiring I gave should be right.
