Hello All,
I'm trying to sort out how to use an analog, needle-style, coild&spring type of panel meter movement. I have a couple of samples to play with, unfortunately I have no infomation about them. On one, the needle rests on the left, on the other, the in the center - this is actually the one I am most interested in using.
For clairty this is the kind of device I'm referring to:
So I'm looking for a sample circuit that shows me how this sort of movement is connected and driven, or just what words to use on Google to find such circuits, and how to figure out details on the samples I have. I'm finding lots of results on meters except for how to do this.
I'm intending to use this movement to indicate whether a signal is above or below a given value - if you think of a guitar tuner, that's probably a helpful example.
Thanks! Patrick Keenan
