<br>I dicked about with some Allegro A1302 devices and found them to be extremely smooth and consistent. Using Gene's 'pen' method I was getting good rotational readings with no dead spots. I'm now using these in a linear fashion with no problems.<br>
<br>I think Gene has a youtube video showing this?<br><br>Roy.<br><br><br><div class="gmail_quote">On 20 October 2012 22:18, <span dir="ltr"><<a href="mailto:dabigboy@cox.net" target="_blank">dabigboy@cox.net</a>></span> wrote:<br>

Question: if you position a couple magnets around a Hall sensor, exactly how much of a complete rotation can the sensor read? IOW, if you rotate the sensor (or the magnets around the sensor) 360*, will you get a relatively linear resistance curve out of the sensor? I'm guessing if you started with the sensor in a position to read lowest (lowest resistance, basically), then at 180* the resistance would be highest, and as you continued the rotation, resistance would start going down again until returning to the original starting point. No?<br>
<br>
If Hall sensors work something like this, then I think I may have a very interesting use for them.<br>
