Hello,
I've had a look at a couple of free online circuit simulators, but struggled a bit to do anything useful with them. I'm trying to find a way of simulating a circuit using op amps, to see if I can achieve what I want using them. I generally find that I don't know where to start because there are 4000 op amps to choose from, or that there isn't a way to get all the inputs and outputs, or components, that I need to play around with. Does anyone have any suggestions of an (ideally free) circuit simulator? (I know it's a bit cheeky to expect good functionality and free to use, but I don't anticipate needing such a thing for any other use)
What I'm trying to do is get a Hall pedal input with a 0.8 - 4.2V range, to give me (via the circuit I create) a 2.5 - 3.9V range output. I then need to be able to activate a reverse switch (either physical or digital) which then changes the output range to 2.5 - 1.1V with the same pedal deflection (i.e. foot flat on the pedal gives 1.1V, releasing the pedal gives 2.5V). I also need the 2.5V output to be maintained while switching from forward to reverse (it will feed into an existing motor controller, which will detect an error and turn off if the signal is lost).
Another poster suggested a set up that will achieve the 2.5 - 3.9V range, and I'd like to develop that to incorporate the other stuff/see if the idea is actually possible.
