Following on from my post of a few days ago ( driving (inputting) the L9110s H-Bridge ) I was a tad optimistic when I said it was now working fine.
Brief re-cap. I have a pulse, 1/3sec duration @ 2 ppmin, debounced, coming from a pendulum master clock, driving a clock dial that I thought needed a pukse every 30 sec of alternate polarity. It did work - but the clock dial was moving at twice the correct speed. The clock motor , which was an ebay buy and is new to me, obviously requires a pulse every minute of alternate polarity.
I've tried every thing I can think of to obtain this using the same chips, but using the other half of the 4013. I couldn't do it.
So.. the question. I don't have a 4081, but before I order one, would this circuit work ? ie..The original 1/3sec duration pulses @ 30 sec intervals are needed to drive the L9110 hbridge every minute and alternate polarity..
