We agree on this, as long as both 0 and both 1 are disallowed.It would be ok. It would work.
I absolutely guarantee it.
The first would have worked, yes, if the bases were not tied together.
See --ETA above your post.Now how do we fulfil the requirements with only 6 more cents allowed in parts?
OP would have a heart attack at the price and the complexity of it.That would be my preferred method, but OP doesn't have PICKit 2
May as well finsih this as we started. SCR has a 5mA holding current, so the LED will keep it on during motor stops and reversals.
Just need the reversal switch to toggle a transistor flip flip/multi(single, actually) vibrator, and the design is essentially finished.
Provided there is no need to stop the motor in a hurry.
