The reason for this is that depending on which side of the gear train you attach the pot from as well as the number of gears in the gear train may be different and could cause the final arrangement to differ in rotational sense than that in the original servo.<p>If the rotational sense is different than the original, the servo motor would turn, which would cause the final shaft to turn as well as the pot, but in a direction that will set the pot to a voltage that is further not closer to the desired voltage. It will keep on turning in this direction until it hits a mechanical stop. If you hook it up this way and the pot has internal mechanical stops, the likely result will be a damaged pot unless you remove power before it hits the mechanical stop on the pot.</p><p>Test the configuration by temporarily removing the gear which drives the pot. Then manually turning the pot in the direction the gear would be driven when the servo is commanded to change to a new position. This will determine if you need to swap the leads on the pot or not.</p><p>If the motor stops before you hit the end limit on the pot, the sense is correct. If not, and it stops if you turn the pot in the opposite direction than the output gear would have turned the pot, you need to reverse the two outside leads on the pot.</p><p>Hope this is not too confusing.</p></p>

The pot was just there to sweep the servo. Of course if you want the pot to reflect the position of the arm, you could either flip the pot around (on the breadboard) or even change the code in the Arduino (just reverse the values in the map command). However, this was just to show the sweep and nothing else. Realistically, the pot wouldn't be there and you'd have a much more complex control system. The purpose here was just to show servo modification, so we weren't really focused on a fully fleshed-out control system.</p>

Were those 24 credits of controls in college a waste? What am I missing?</p>

In particular, it has no support for any of the newer instruction sets like MMX, SSE, or SSE2 - a lot of modern software expects these, especially the kind of x86-only or tuned-for-x86 code that might otherwise give this an advantage over ARM platforms.</p>

I actually started counting your use of actually and I actually lost count - it actually got close to actually one 'actually' per sentence. 'Actually' actually loses all meaning if you actually overuse the word. Actually, I hope this makes a point as it's actually getting a little distracting to an otherwise interesting and informative post. (recursive and hypocritcal as this actually is - sorry).</p>

I don't think it's hot enough to require a heatsink, under normal conditions at least. <a href="https://communities.intel.com/message/207619" rel="nofollow">Intel's FAQ</a> says about the same.<p>Heh, actually, one of their <a href="https://communities.intel.com/docs/DOC-22272" rel="nofollow">example sketches here</a> uses the Quark's internal temp sensor to turn it into a touch sensor. So they must not be too worried about the heat being damaging :P.</p></p>
